Description
This circuit consists of two independent, high-
gain, internally frequency-compensated operational
amplifiers, designed specifically for automotive
and industrial control systems. It operates from a
single power supply over a wide range of
voltages. The low power supply drain is
independent of the magnitude 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
implemented in single power supply systems. For
example, these circuits can be directly supplied
from standard +5V which is used in logic systems
and will easily provide the required interface
electronics without requiring any additional power
supply.

Wafer form
In linear mode, the input common-mode voltage
range includes ground and the output voltage can
also swing to ground, even though operated from
a single power supply.
