MOTOROLA ANALOG IC DEVICE DATA

Micropower Programmable

Operational Amplifier

This extremely versatile operational amplifier features low power

consumption and high input impedance. In addition, the quiescent currents

within the device may be programmed by the choice of an external resistor

value or current source applied to the Iset input. This allows the amplifier’s

characteristics to be optimized for input current and power consumption

despite wide variations in operating power supply voltages.
