This document describes the features and characteristics of the S-89430/89431 series of micro analog CMOS operational amplifiers, including low voltage operation, low power consumption, wide input-output voltage range, etc. This series is suitable for battery-powered small mobile devices.
The S-89430/89431 series are rail‑to‑rail CMOS arithmetic amplifiers designed for low‑voltage, low‑power applications such as portable devices, cameras and imaging equipment. The series includes single‑channel (S‑89430A/89431A) and dual‑channel (S‑89430B/89431B) versions, each offering rail‑to‑rail input and output ranges.
The datasheet provides detailed electrical characteristics, pin configurations for SC‑88A, SOT‑23‑5, SNT‑8A and TMSOP‑8 packages, and typical application information. Key specifications include a supply voltage range of 0.9 V to 5.5 V, quiescent current of 0.5 µA per channel, and input offset voltages of 10 mV (S‑89430) or 5 mV (S‑89431). This manual is written in Japanese.
