DESCRIPTION
This circuit consists of four independent, high
gain, internally frequency compensated operation-
al amplifiers which were designed specially for au-
tomotive and industrial control systems. It oper-
ates from a single power supply over a wide range
of voltages. Operation from split power supplies is
also possible. All the pins are protected against
electrostatic discharges up to 2000v.
