Description

This circuit consists of two independent, high gain

operational amplifiers with frequency

compensation implemented internally. It is

designed specifically for aerospace and defense

applications. The circuit operates from a single

power supply over a wide range of voltages. Low

power supply drain is independent of the

magnitude of the power supply voltage.

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.
