It might be pointed out that the advice given here is applicable to practically any IC op amp, although the exact reason why may differ with different de- vices, When driving either input from a low-impedance source, a limiting resistor should be placed in series. with the input lead to limit the peak instantaneous output current of the source to something less than 100 mA. This is especially important when the inputs go outside a piece of equipment where they could accidentally be connected to high voltage sources, Large capacitors on the input (greater than 0.4 pF) should be treated as a low source impedance and isolated with a resistor, Low impedance sources do not cause a problem unless their output voltage.exceeds the supply volt. age. However, the supplies go to zero when they are turned off, so the isolation is usually needed. The output circuitry is protected against damage from shorts to ground. However, when the amplifier output is connected to a test point, it should be isolated by a limiting resistor, as test points frequently get shorted to bad places, Further, when the amplifer drives a load external to the equipment, it Is also advisable to use some sort of limiting resistance to preclude mishaps, **Pin connections shown are for 8-pin packages, T-79-05-10 ~ |] Compensating for Stray Input Capacitances or Large Feedback Resistor c2 INPUT OUTPUT RiCs O2= "Ep 1 R3 it oureuT Cy TL/H/7762-27 isolating Large Capacitive Loads Cy TL/H/7752-28 Precautions should be taken to insure. that the power sup- plies for the integrated circuit never become reversed even under transient conditions. With reverse voltages greater than 1V, the IC will conduct excessive current, fus- ing internal aluminum interconnects. {f there is a possibility of this happening, clamp diodes with a high peak current rating should be installed on the supply lines. Reversal of the voltage between V+ and V will always cause a prob- lem, although reversals with respect to ground may also give difficulties in Many circuits. The minimum values given for the frequency compensation Capacitor are stable only for source resistances less than 10 kQ, stray capacitances on the summing junction less than 5 pF and capacitive loads smaller than 100 pF. If any of these conditions are not met, it becomes necessary to overcompensate the amplifier with a larger compensation capacitor, Alternately, lead capacitors can be used in the feedback network to negate the effect of stray capacitance and large feedback resistors or an RC network can be add- ed to isolate capacitive loads, Although the LM101A is relatively unaffected by supply by- passing, this cannot be ignored altogether. Generally it is hecessary to bypass the supplies to ground at least once on every circuit card, and more bypass points may be required if more than five amplifiers are used. When feed-forward compensation is employed, however, it Is advisable to by- pass the supply leads of each amplifier with low Inductance Capacitors because of the higher frequencies involved. 3-367 VEOEWT/VLOZW1/VLOLWTNATL SEMICOND (LINEAR) eee D = 6501124 0064254 1 Typical Applications** (continued) Standard Compensation and Offset Balancing Circuit LM101A/LM201A/LM301A 1-79-05-10 Fast Summing Amplifier View Power Bandwidth: 250 kHz Smait Signal Bandwiidth: 3.5 MHz Slew Rate: 10V/ps TL/H/7752~30 TWH/7762-28 Fast Voltage Follower Bilateral Current Source 2 Vour c2 Vow 300 pF Power Bandwidth: 15 kHz.
