This document describes the features and characteristics of the Zero-Drift, Single-Supply, Rail-to-Rail Input/Output Operational Amplifier AD8628/AD8629/AD8630, including lowest auto-zero amplifier noise, low offset voltage, input offset drift, rail-to-rail input and output swing, 5V single-supply operation, high gain, CMRR, and PSRR, very low input bias current, low supply current, and short overload recovery time.
The AD8628, AD8629, and AD8630 are zero‑drift, single‑supply, rail‑to‑rail input/output operational amplifiers with ultra‑low offset voltage, bias current, and noise. They are suited for automotive sensors, pressure and position sensors, strain‑gage amplifiers, medical instrumentation, thermocouple amplifiers, precision current sensing, and photodiode amplification.
These devices are offered in multiple surface‑mount packages (5‑lead TSOT, 5‑lead SOT‑23, 8‑lead SOIC, 8‑lead MSOP, 14‑lead SOIC, 14‑lead TSSOP) and operate from 2.7 V to 5 V supplies. The document includes detailed electrical characteristics, absolute maximum ratings, thermal data, typical performance curves, and an ordering guide.
