Analog Devices AD8551/AD8552/AD8554 Zero‑Drift Operational Amplifier Datasheet
The AD855x family provides ultra‑low offset voltage (as low as 0 µV), low drift (0.005 µV/°C), and low input bias current (typical 20 pA). They operate from a single supply of +2.7 V to +5 V and are specified for an extended industrial/automotive temperature range of –40 °C to +125 °C. These amplifiers are suited for precision sensor interfaces, medical instrumentation, and thermocouple amplification.
The datasheet includes detailed electrical characteristics, ordering information, absolute maximum ratings, and functional description of the auto‑zero architecture. It also provides application notes such as high‑side and low‑side load‑current monitoring circuits.
