The AD8551/AD8552/AD8554 are zero-drift, single-supply, rail-to-rail input/output operational amplifiers from Analog Devices. The family has ultralow offset, drift, and bias current, and is guaranteed to operate from 2.7V to 5V with a single supply.
The AD8554 belongs to the AD855x family of zero‑drift, single‑supply operational amplifiers. It offers an ultralow offset voltage, extremely low input bias current, rail‑to‑rail I/O swing and high CMRR, making it suitable for precision sensor and instrumentation applications.
The quad‑package device is offered in 14‑lead narrow SOIC and 14‑lead TSSOP packages and is rated for operation from –40 °C to +125 °C. The datasheet includes detailed electrical characteristics, absolute maximum ratings, thermal data, typical performance graphs, and an ordering guide.
