TECHNICAL DATA MICROPOWER PROGRAMMABLE OPERATIONAL AMPLIFIER IL1776 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.
