DESCRIPTION
This circuit consists of four independent, high gain,
internally frequency compensated operational amplifiers which were designed specifically for automotive and industrial control systems. It 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 of the magnitude of the power supply
voltage.
