Overview - S-89430/89431
0.5 µA Rail-to-Rail CMOS Operational Amplifier S-89430/89431 Series
The mini-analog series is a group of ICs that incorporate a general purpose analog circuit in a small package.
The S-89430/89431 Series is a CMOS type operational amplifier that feature Rail-to-Rail*1 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).

Features
- Lower operating voltage than the conventional general-purpose: Vdd = 0.9 V to 5.5 V
- Low current consumption (per circuit): Idd = 0.5 µA Typ.
- Wide I/O voltage range (Rail-to-Rail): Vcmr = Vss to Vdd
- Low input offset voltage: Vio = 10.0 mV Max. (S-89430 Series) Vio = 5.0 mV Max. (S-89431 Series)
- No external capacitors required for internal phase compensation
- Small packages: SC-88A, SOT-23-5, SNT-8A, TMSOP-8
- Lead-free product
Applications
- Mobile phones
- Notebook PCs
