The mini-analog series is a group of ICs that incorporate a general purpose analog circuit in a small package.
*1
The S-89430/89431 Series is a CMOS type operational amplifier that feature Rail-to-Rail I/O and an internal phase
compensation circuit, and operates at a lower voltage with lower current consumption. These features make this product
the ideal solution for small battery-powered portable equipment.
These features enable driving at a lower voltage (from 0.9 V) and with lower current consumption (0.5
μA).
The S-89430A/89431A Series is a single operational amplifier (one circuit).
The S-89430B/89431B Series is a dual operational amplifier (two circuits).
