The mini-analog series is a group of ICs that incorporate a general purpose analog circuit in a small package. The S-89110A/89120A is a CMOS type single operational amplifier that has a phase compensation circuit, and that can be driven at a lower voltage with lower current consumption than existing bipolar operational amplifiers. These features make this product the ideal solution for small battery-powered portable equipment. The S-89110A/89120A is a single operational amplifier.
