The mini-analog series is a group of ICs that incorporate a

general purpose analog circuit in a small package.

The

S-89430A/89431A

is

a

CMOS

type

operational

amplifier that feature Rail-to-Rail*

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.

These features enable driving at a lower voltage (from 0.9

V) and with lower current consumption (0.5

μA)

The S-89430A/89431A is a single operational amplifier.
