Description
This circuit consists of two independent, high
gain, internally frequency compensated which
were designed 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
magnitude of the power supply voltage.

low power supply drain is independent of the

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
with off the standard +5V which is used in logic
systems and will easily provide the required
interface electronics without requiring any
additional power supply.

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.
