DESCRIPTION
The AU2902 consists of four independent, high-gain, internally
frequency-compensated operational amplifiers designed specifically
to operate from a single power supply over a wide range of voltages.
UNIQUE FEATURES
In the linear mode, the input common-mode voltage range includes
ground and the output voltage can also swing to ground, even
though operated from only a single power supply voltage.
The unity gain crossover frequency and the input bias current are
temperature-compensated.
FEATURES

Large DC voltage gain: 100 dB
Wide bandwidth (unity gain): 1 MHz (temperature-compensated)

NOTES:
1. Derate above 25
C at the following rates:
N package at 11.4 mW/
C
D package at 8.3 mW/
C
2. Short-circuits from the output to V
CC
+ can cause excessive heating and eventual destruction. The maximum output current is approximately
40 mA, independent of the magnitude of V
CC
. At values of supply voltage in excess of +15 V
DC
continuous short-circuits can exceed the
power dissipation ratings and cause eventual destruction.
3. 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 bias clamps. In addition, there is also lateral NPN parasitic
transistor action on the IC chip. This action can cause the output voltages of the op amps to go to the V+ rail (or to ground for a large
overdrive) during the time that the input is driven negative.

with V
CC
from 5 V to 30 V and over full input common-mode range (0 V
DC
+ to V
CC
1.5 V).
2. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of
the output so no loading change exists on the input lines.
3. The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3 V. The upper end of
the common-mode voltage range is V
CC
1.5, but either or both inputs can go to +32 V without damage.
4. Short-circuits from the output to V
CC
can cause excessive heating and eventual destruction. The maximum output current is approximately
40 mA independent of the magnitude of V
CC
. At values of supply voltage in excess of +15 V
DC
, continuous short-circuits can exceed the
power dissipation ratings and cause eventual destruction. Destructive dissipation can result from simultaneous shorts on all amplifiers.
5. Due to 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 coupling increases at higher frequencies.
