This document describes the features and characteristics of the low noise, precision, 16 V, CMOS, rail-to-rail operational amplifiers AD8663/AD8667/AD8669.
The AD866x family provides low offset voltage, ultra‑low input bias current, and low noise performance for sensor front ends, transimpedance amplifiers, and precision instrumentation. They operate from a single 5 V to 16 V supply or dual supplies (+2.5 V to +8 V) and are specified over an industrial temperature range of –40 °C to +125 °C.
These amplifiers are offered in several surface‑mount packages, including 8‑lead SOIC, 8‑lead LFCSP, 8‑lead MSOP, 14‑lead SOIC, and 14‑lead TSSOP. The document includes detailed electrical characteristics, absolute maximum ratings, thermal resistance data, typical performance curves, and an ordering guide for each part number.
