Semiconductor

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 I
input. This allows the amplifier`s characteristics to be optimized for input current and power
consumption despite wide variations in operating power supply voltages.
