MINI ANALOG SERIES
0.5 μA Rail-to-Rail CMOS OPERATIONAL AMPLIFIER
S-89430A/89431A
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*1 I/O and an internal 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.
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.
