DESCRIPTION

These circuits consist of four independent, high

gain, internally frequency compensated operation-

al amplifiers. They operate 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.

All the pins are protected against electrostatic dis-

charges up to 2000V (as a consequence, the input
