This document describes the features and characteristics of the AD627 model from Analog Devices. The AD627 is a micropower, single and dual supply, rail-to-rail instrumentation amplifier. It features a wide power supply range, easy gain set with one external resistor, high accuracy DC performance, and excellent AC specifications.
The AD627 is a micropower instrumentation amplifier that operates from +2.2 V to +18 V (single supply) or dual supplies up to +15 V. It offers rail‑to‑rail output swing, low quiescent current (85 µA max), and gain set by a single external resistor, ranging from 5 (no resistor) to 1000.
The datasheet provides detailed electrical specifications, typical performance graphs, ordering information, and example application circuits such as bridge configurations, 4‑20 mA receivers, and thermocouple amplifiers.
