DESCRIPTION
This circuit consists of two independent, high gain,
internally frequency compensated which were de-
signed specifically for automotive and industrial
control system. It operates from a single power
supply over a wide range of voltages. The low
power supply drain is independent of the magni-
tude of the power supply voltage.
Application areas include transducer amplifiers,
dc gain blocks and all the conventional op-amp
circuits which now can be more easily implement-
ed in single power supply systems. For example,
these circuits can be directly supplied with off the
standard +5V which is used in logic systems and
will easily provide the required interface electron-
ics without requiring any additional power supply.
In the linear mode the input common-mode volt-
age range includes ground and the output voltage
can also swing to ground, even though operated
from only a single power supply voltage.

Short-circuits from the output to V
cc
can cause excessive heating if Vcc
+
> 15V. The maximum output current is approximately 40mA,
independent of the magnitude of V

. Destructive dissipation can result from simultaneous short-circuits on all amplifiers.

3.
This input current only exists when the voltage values applied on the inputs is beyond the supply voltage lines limits. This is not destructive if the
current is limited to 5mA as mentioned and normal output will set up again for input voltage higher than -0.3V

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 charge
change exists on the input lines
3.
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.
4.
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 frequencies.
