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 magni-
tude of the power supply voltage.
