MOTOROLA ANALOG IC DEVICE DATA
The MC3476 is a low cost selection of the popular industry standard
MC1776 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.
