MOTOROLA ANALOG IC DEVICE DATA
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.
