DESCRIPTION
This circuit consists of four independent, high
gain, internally frequency compensated operational amplifiers which were designed specially for automotive and industrial control systems. It operates from a single power supply over a wide range
of voltages. Operation from split power supplies is
also possible. All the pins are protected against
electrostatic discharges up to 2000v.

Short-circuit from the output to VCC can cause excessive heating if V CC > 15V. The maximum output current is approximately 40mA independent of
the magnitude of VCC. Destructive dissipation can result from simultaneous short-circuit on all amplifiers.
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 diodes clamps. In addition to this 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 VCC voltage 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.

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 charge
change exists on the input lines
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 VCC+ –1.5V, but either or both inputs can go to +32V without damage.
Due to the proximity of external components insure that coupling is not originating via stray capacitance between these external parts. This typically
can be detected as this type of capacitance increases at higher frequences.
