Description

This circuit consists of four independent, high gain

operational amplifiers which employ internal

frequency compensation and are specifically

designed for aerospace and defense systems.

The device operates from a single power supply

over a wide range of voltages. Operation from

split power supplies is also possible and the low-

power supply current drain is independent from

the power supply voltage magnitude.
