DESCRIPTION

This circuit consists of four independent, high gain,

internally frequency compensated operational am-

plifiers whichwere designedspecificallyforautomo-

tive and industrial control systems. It operatesfrom

a single power supply over a wide range of volt-

ages. Operation from split power supplies is also

possible and the low power supply current drain is

independentof the magnitude of the power supply

voltage.

Notes : 1. Short-circuits from the output to V_CCcan cause excessive heating if V_{C C}> 15V. The maximum output current

is approximately 40mA independent of the magnitude of V_{C C}. Destructive di ssipation can result from simul ta-

neous short-circuit on all amplifiers.

2. The direction of the input current is out of the IC. This current is essentially constant, independent of the state

of the output so no loading change exists on the input lines.

3. V_o= 1.4V, R_s= 0Ω, 5V < V_CC< 30V, 0 < V_ic< V_CC- 1.5V

4. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more

than 0.3V. The upper end of the common-mode voltage range is V_CC- 1.5V, but either or both inputs can go

to +32V without damage.

5. Due to the proximity of external components insure that coupling is not originating via stray capacitance be-

tween these external parts. This typically can be detected as this type of capacitance increases at higher fre-

quences.

6. This input current only exists when the voltage at any of the input leads is driven negative. It is due to the

collector-base junction of the input PNP transistor becoming forward biased and thereby acting as input di-

odes clamps. In addition to thi s diode action, there is also NPN parasitic action on the IC chip. this transistor

action can cause the output voltages of the Op-amps to go to the V_CCvoltage level (or to ground for a large

overdrive) for the time duration than an input is driven negative.

This is not destructive and normal output will set up again for input voltage higher than -0.3V.
