The mini-analog series is a group of ICs that incorporate a general purpose analog circuit in a small package. The S-89210A/89220A is a CMOS type comparator that has a phase compensation circuit, and that can be driven at a lower voltage with lower current consumption than existing bipolar comparators. These features make this product the ideal solution for small battery-powered portable equipment. The S-89210A/89220A is a single comparator.
