CMOS Operational Amplifier S-89110/89120 Series

The mini-analog series is a group of ICs that incorporate a general purpose analog circuit in a small package. The S-89110/89120 Series is a CMOS type operational amplifier that has a phase compensation circuit, and operates at a low voltage with low current consumption. These features make this product the ideal solution for small battery-powered portable equipment. The S-89110A/120A Series is a single operational amplifier (one circuit). The S-89110B/120B Series is a dual operational amplifier (two circuits).
