DESCRIPTION
These circuits consist of four independent, high
gain, internally frequency compensated operational
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 discharges up to 2000V (as a consequence, the input
voltages must not exceed the magnitude of VCC+ or
VCC-.)
