LOW POWER LOW OFFSET VOLTAGE DUAL COMPARATORS AS393/393A

BCD Semiconductor Manufacturing Limited

Data Sheet

Jan. 2011 Rev. 2. 1

General Description

The AS393/393A consist of two independent precision

voltage comparators with a typical offset voltage of

1.0mV and high gain. They are specifically designed to

operate from a single power supply over wide range of

voltages. Operation from split power supply is also

possible and the low power supply current drain is

independent of the magnitude of the power supply

voltage.

The AS393/393A series are compatible with industry

standard 393. AS393A has more stringent input offset

voltage than AS393.

The AS393 is available in standard DIP-8, SOIC-8

TSSOP-8 and MSOP-8 packages, AS393A is available

in standard DIP-8 and SOIC-8 packages.

Recommended Operating Conditions

Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the

device. These are stress ratings only, and functional operation of the device at these or any other conditions

beyond those indicated under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Max-

imum Ratings" for extended periods may affect device reliability.

Note 2: This input current will only exist when the voltage at any of the input leads is driven negative. It is due to

the collector-base junction of the input PNP transistors becoming forward biased and thereby acting as input diode

clamps. In addition to this diode action, there is also lateral NPN parasitic transistor action on the IC chip. This

transistor action can cause the output voltages of the comparators to go to the V+ voltage level (or to ground for a

large overdrive) for the time duration that an input is driven negative. This is not destructive and normal output

states will re-establish when the input voltage, which was negative, again returns to a value greater than -0.3 VDC

(at 25oC).

Limits in standard typeface are for TA=25oC, bold typeface applies over TA=-40oC to 85oC (Note 3), VCC=5V, GND=0V,

unless otherwise specified.

Note 3: These specifications are limited to -40oC≤ TA ≤85oC. Limits over temperature are guaranteed by design,

but not tested in production.

Note 4: The input common-mode voltage of either input signal voltage should not be allowed to go negatively by

more than 0.3V (at 25oC). The upper end of the common-mode voltage range is VCC-1.5V (at 25oC), but either or

both inputs can go to +36V without damages, independent of the magnitude of the VCC.
