DESCRIPTION
The LMC7211 is a micropower CMOS comparator available in the space saving SOT23-5 package. This makes
the comparator ideal for space and weight critical designs. The LMC7211 is supplied in two offset voltage
grades, 5 mV and 15 mV.
The main benefits of the Tiny package are most apparent in small portable electronic devices, such as mobile
phones, pagers, notebook computers, personal digital assistants, and PCMCIA cards. The rail-to-rail input
voltage makes the LMC7211 a good choice for sensor interfacing, such as light detector circuits, optical and
magnetic sensors, and alarm and status circuits.
The Tiny Comparator's outside dimensions (length x width x height) of 3.05mm x 3.00mm x 1.43mm allow it to fit
into tight spaces on PC boards.

APPLICATION INFORMATION
Benefits of the LMC7211 Tiny Comparator
Size. The small footprint of the SOT 23-5 packaged Tiny Comparator, (0.120 x 0.118 inches, 3.05 x 3.00 mm)
saves space on printed circuit boards, and enable the design of smaller electronic products. Because they are
easier to carry, many customers prefer smaller and lighter products.
Height. The height (0.056 inches, 1.43 mm) of the Tiny Comparator makes it possible to use it in PCMCIA type
III cards.
Simplified Board Layout. The Tiny Comparator can simplify board layout in several ways. First, by placing a
comparator where comparators are needed, instead of routing signals to a dual or quad device, long pc traces
may be avoided.
By using multiple Tiny Comparators instead of duals or quads, complex signal routing and possibly crosstalk can
be reduced.
Low Supply Current. The typical 7 μA supply current of the LMC7211 extends battery life in portable
applications, and may allow the reduction of the size of batteries in some applications.
Wide Voltage Range. The LMC7211 is characterized at 15V, 5V and 2.7V. Performance data is provided at
these popular voltages. This wide voltage range makes the LMC7211 a good choice for devices where the
voltage may vary over the life of the batteries.
Digital Outputs Representing Signal Level. Comparators provide a high or low digital output depending on the
voltage levels of the (+) and () inputs. This makes comparators useful for interfacing analog signals to
microprocessors and other digital circuits. The LMC7211 can be thought of as a one-bit a/d converter.
Push-Pull Output. The push-pull output of the LMC7211 is capable of both sourcing and sinking milliamp level
currents even at a 2.7 volt supply. This can allow the LMC7211 to drive multiple logic gates.
Driving LEDs (Light Emitting Diodes). With a 5 volt power supply, the LMC7211's output sinking current can
drive small, high efficiency LEDs for indicator and test point circuits. The small size of the Tiny package makes it
easy to find space to add this feature to even compact designs.
Input range to Beyond Rail to Rail. The input common mode range of the LMC7211 is slightly larger than the
actual power supply range. This wide input range means that the comparator can be used to sense signals close
to the power supply rails. This wide input range can make design easier by eliminating voltage dividers,
amplifiers, and other front end circuits previously used to match signals to the limited input range of earlier
comparators. This is useful to power supply monitoring circuits which need to sense their own power supply, and
compare it to a reference voltage which is close to the power supply voltage. The wide input range can also be
useful for sensing the voltage drop across a current sense resistor for battery chargers.
Zero Crossing Detector. Since the LMC7211's common mode input range extends below ground even when
powered by a single positive supply, it can be used with large input resistors as a zero crossing detector.
Low Input Currents and High Input Impedance. These characteristics allow the LMC7211 to be used to sense
high impedance signals from sensors. They also make it possible to use the LMC7211 in timing circuits built with
large value resistors. This can reduce the power dissipation of timing circuits. For very long timing circuits, using
high value resistors can reduce the size and cost of large value capacitors for the same R-C time constant.
Direct Sensor Interfacing. The wide input voltage range and high impedance of the LMC7211 may make it
possible to directly interface to a sensor without the use of amplifiers or bias circuits. In circuits with sensors
which can produce outputs in the tens to hundreds of millivolts, the LMC7211 can compare the sensor signal
with an appropriately small reference voltage. This may be done close to ground or the positive supply rail. Direct
sensor interfacing may eliminate the need for an amplifier for the sensor signal. Eliminating the amplifier can
save cost, space, and design time.
Low Voltage Operation
Comparators are the common devices by which analog signals interface with digital circuits. The LMC7211 has
been designed to operate at supply voltages of 2.7V without sacrificing performance to meet the demands of 3V
digital systems.

At supply voltages of 2.7V, the common-mode voltage range extends 200 mV (guaranteed) below the negative
supply. This feature, in addition to the comparator being able to sense signals near the positive rail, is extremely
useful in low voltage applications.
Figure 3. Even at Low-Supply Voltage of 2.7V, an Input Signal which Exceeds the Supply Voltages
Produces No Phase Inversion at the Output
At V+= 2.7V propagation delays are tPLH =4μs and tPHL =4μs with overdrives of 100 mV.
Please refer to the performance curves for more extensive characterization.
Shoot-Through Current
The shoot-through current is defined as the current surge, above the quiescent supply current, between the
positive and negative supplies of a device. The current surge occurs when the output of the device switches
states. The shoot-through current results in glitches in the supply voltages. Usually, glitches in the supply lines
are prevented by bypass capacitors. When the glitches are minimal, the value of the bypass capacitors can be
reduced.

Shoot-Through Current

SNOS746F MAY 2004REVISED JANUARY 2013
Figure 5. Measurement of the Shoot-Through Current
From Figure 5, the shoot-through current for the LMC7211 can be calculated to be 0.2 mA (typical), and the
duration is 1 μs. The values needed for the bypass capacitors can be calculated as follows:
Area of Δ= ½ (1 μs × 200 μA)
= 100 pC
The capacitor needs to supply 100 picocolumb. To avoid large shifts in the comparator threshold due to changes
in the voltage level, the voltage drop at the bypass capacitor should be limited to 100 mV or less.
The charge needed (100 picocolumb) and the allowable voltage drop (100 mV) will give us the minimum
capacitor value required.
ΔQ=C(ΔV)
C = ΔQ/ΔV = 100 picocolumb/100 mV
C = 10-10/10-1 = 10-9 = 1 nF = 0.001 μF
10-9 = 1 nF = 0.001 μF
The voltage drop of 100 mV will cause a threshold shift in the comparator. This threshold shift will be reduced
by the power supply rejection ratio, (PSRR). The PSRR which is applicable here is not the DC value of PSRR
(80 dB), but a transient PSRR which will be usually about 20 dB–40 dB, depending on the circuit and the speed
of the transient. This will result in an effective threshold shift of about 1 mV to 10 mV.
For precision and level sensing circuits, it is generally a good goal to reduce the voltage delta on the power
supply to a value equal to or less than the hysteresis of the comparator circuit. If the above circuit was to be used
with 50 mV of hysteresis, it would be reasonable to increase the bypass capacitor to 0.01 μF to reduce the
voltage delta to 10 mV. Larger values may be useful for obtaining more accurate and consistent switching.
Note that the switching current of the comparator can spread to other parts of the board as noise. The bypass
capacitor reduces this noise. For low noise systems this may be reason to make the capacitor larger.
For non-precision circuits, such as using a comparator to determine if a push-button switch is on or off, it is often
cheaper and easier to use a larger value of hysteresis and a small value or bypass capacitance. The low shoot-
through current of the LMC7211 can allow the use of smaller and less expensive bypass capacitors in non-critical
circuits.

Output Short Circuit Current
The LMC7211 has short circuit protection of 40 mA. However, it is not designed to withstand continuous short
circuits, transient voltage or current spikes, or shorts to any voltage beyond the supplies. A resistor in series with
the output should reduce the effect of shorts. For outputs which send signals off PC boards additional protection
devices, such as diodes to the supply rails, and varistors may be used.
Hysteresis
If the input signal is very slow or very noisy, the comparator output might trip several times as the input signal
passes through the threshold. Using positive feedback to add hysteresis to the switching can reduce or eliminate
this problem. The positive feedback can be added by a high value resistor (RF). This will result in two switching
thresholds, one for increasing signals and one for decreasing signals. A capacitor can be added across RFto
increase the switching speed and provide more short term hysteresis. This can result in greater noise immunity
for the circuit.
See Figure 6,Figure 7 and Figure 8.
Note that very heavy loading of the comparator output, such as LED drive or bipolar logic gates, will change the
output voltage and shift the voltage thresholds.

Input Protection
If input signals are like to exceed the common mode range of the LMC7211, or it is likely that signals may be
present when power is off, damage to the LMC7211 may occur. Large value (100 kΩto MΩ) input resistors may
reduce the likelihood of damage by limiting the input currents. Since the LMC7211 has very low input leakage
currents, the effect on accuracy will be small. Additional protection may require the use of diodes, as shown in
Figure 9. Note that diode leakage current may affect accuracy during normal operation. The R-C time constant of
RIN and the diode capacitance may also slow response time.
Figure 9.
Layout Considerations
The LMC7211 is not an especially fast comparator, so high speed design practices are not required. The
LMC7211 is capable of operating with very high impedance inputs, so precautions should be taken to reduce
noise pickup with high impedance (100 kΩand greater) designs and in electrically noisy environments.
Keeping high value resistors close to the LMC7211 and minimizing the size of the input nodes is a good practice.
With multilayer designs, try to avoid long loops which could act as inductors (coils). Sensors which are not close
to the comparator may need twisted pair or shielded connections to reduce noise.
Open Drain Output, Dual Versions
The LMC7221 is a comparator similar to the LMC7211, but with an open drain output which allows the output
voltage to be different (higher or lower) than the supply voltage. The open drain output is like the open collector
output of a logic gate. This makes the LMC7221 very useful for mixed voltage systems. Many systems will have
different voltages for the analog and microprocessor sections. Please see the LMC7221 datasheet for details.
The performance of the LMC7211 is available in dual devices. Please see the LMC6762 datasheet for details on
a dual push-pull output device. For a dual device with open drain outputs, please see the LMC6772 datasheet.

Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish
value exceeds the maximum column width.

IMPORTANT NOTICE
Texas Instruments Incorporated (TI) reserves the right to make corrections, enhancements, improvements and other changes to its
semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest issue. Buyers
should obtain the latest relevant information before placing orders and should verify that such information is current and complete.
TI’s published terms of sale for semiconductor products (http://www.ti.com/sc/docs/stdterms.htm) apply to the sale of packaged integrated
circuit products that TI has qualified and released to market. Additional terms may apply to the use or sale of other types of TI products and
services.
Reproduction of significant portions of TI information in TI data sheets is permissible only if reproduction is without alteration and is
accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such reproduced
documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements
different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the
associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements.
Buyers and others who are developing systems that incorporate TI products (collectively, “Designers”) understand and agree that Designers
remain responsible for using their independent analysis, evaluation and judgment in designing their applications and that Designers have
full and exclusive responsibility to assure the safety of Designers' applications and compliance of their applications (and of all TI products
used in or for Designers’ applications) with all applicable regulations, laws and other applicable requirements. Designer represents that, with
respect to their applications, Designer has all the necessary expertise to create and implement safeguards that (1) anticipate dangerous
consequences of failures, (2) monitor failures and their consequences, and (3) lessen the likelihood of failures that might cause harm and
take appropriate actions. Designer agrees that prior to using or distributing any applications that include TI products, Designer will
thoroughly test such applications and the functionality of such TI products as used in such applications.
TI’s provision of technical, application or other design advice, quality characterization, reliability data or other services or information,
including, but not limited to, reference designs and materials relating to evaluation modules, (collectively, “TI Resources”) are intended to
assist designers who are developing applications that incorporate TI products; by downloading, accessing or using TI Resources in any
way, Designer (individually or, if Designer is acting on behalf of a company, Designer’s company) agrees to use any particular TI Resource
solely for this purpose and subject to the terms of this Notice.
TI’s provision of TI Resources does not expand or otherwise alter TI’s applicable published warranties or warranty disclaimers for TI
products, and no additional obligations or liabilities arise from TI providing such TI Resources. TI reserves the right to make corrections,
enhancements, improvements and other changes to its TI Resources. TI has not conducted any testing other than that specifically
described in the published documentation for a particular TI Resource.
Designer is authorized to use, copy and modify any individual TI Resource only in connection with the development of applications that
include the TI product(s) identified in such TI Resource. NO OTHER LICENSE, EXPRESS OR IMPLIED, BY ESTOPPEL OR OTHERWISE
TO ANY OTHER TI INTELLECTUAL PROPERTY RIGHT, AND NO LICENSE TO ANY TECHNOLOGY OR INTELLECTUAL PROPERTY
RIGHT OF TI OR ANY THIRD PARTY IS GRANTED HEREIN, including but not limited to any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
regarding or referencing third-party products or services does not constitute a license to use such products or services, or a warranty or
endorsement thereof. Use of TI Resources may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
TI RESOURCES ARE PROVIDED “AS IS” AND WITH ALL FAULTS. TI DISCLAIMS ALL OTHER WARRANTIES OR
REPRESENTATIONS, EXPRESS OR IMPLIED, REGARDING RESOURCES OR USE THEREOF, INCLUDING BUT NOT LIMITED TO
ACCURACY OR COMPLETENESS, TITLE, ANY EPIDEMIC FAILURE WARRANTY AND ANY IMPLIED WARRANTIES OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT OF ANY THIRD PARTY INTELLECTUAL
PROPERTY RIGHTS. TI SHALL NOT BE LIABLE FOR AND SHALL NOT DEFEND OR INDEMNIFY DESIGNER AGAINST ANY CLAIM,
INCLUDING BUT NOT LIMITED TO ANY INFRINGEMENT CLAIM THAT RELATES TO OR IS BASED ON ANY COMBINATION OF
PRODUCTS EVEN IF DESCRIBED IN TI RESOURCES OR OTHERWISE. IN NO EVENT SHALL TI BE LIABLE FOR ANY ACTUAL,
DIRECT, SPECIAL, COLLATERAL, INDIRECT, PUNITIVE, INCIDENTAL, CONSEQUENTIAL OR EXEMPLARY DAMAGES IN
CONNECTION WITH OR ARISING OUT OF TI RESOURCES OR USE THEREOF, AND REGARDLESS OF WHETHER TI HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
Unless TI has explicitly designated an individual product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949
and ISO 26262), TI is not responsible for any failure to meet such industry standard requirements.
Where TI specifically promotes products as facilitating functional safety or as compliant with industry functional safety standards, such
products are intended to help enable customers to design and create their own applications that meet applicable functional safety standards
and requirements. Using products in an application does not by itself establish any safety features in the application. Designers must
ensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products in
life-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use.
Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., life
support, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, all
medical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S.
TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product).
Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applications
and that proper product selection is at Designers’ own risk. Designers are solely responsible for compliance with all legal and regulatory
requirements in connection with such selection.
Designer will fully indemnify TI and its representatives against any damages, costs, losses, and/or liabilities arising out of Designer’s non-
compliance with the terms and provisions of this Notice.
