DESCRIPTION
These circuits consist of four independent, high
gain, internally frequency compensated operational
amplifiers which were designed specifically for auto-
motive and industrial control systems. They operate
from a single power supply over a wide range of
voltages. Operation from split power supplies is also
possible and the low power supply current drain is
independent of the magnitude of the power supply
voltage.

Notes : 1. Short-circuits from the output to V CC can cause excessive heating if V CC > 15V. The maximum output current
is approximately 40mA independent of the magnitude of V CC . 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 =0
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 e xternal parts. This typically can be detected as this type o f 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 this diode action, there is also NPN parasiti c a ction on the IC chip. thi s transistor
action can cause the output voltages of the Op-amps to go to the V CC 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.
