AD8571/AD8572/AD8574 are AD company's zero-drift, single-supply, rail-to-rail input/output operational amplifiers. Its features are low bias current, low input drift, high gain, high CMRR, high PSRR, wide dynamic range, low supply current and fast recovery time. This series of amplifiers is suitable for temperature sensors, pressure sensors, precision current sensing, strain gauge amplifiers, medical instruments, thermocouple amplifiers and other applications.
The AD857x family provides zero‑drift, single‑supply operational amplifiers with rail‑to‑rail input and output swings. They feature ultralow offset voltage (1 pV), ultralow input bias current (20 pA), and high CMRR (up to 130 dB), making them suitable for precision sensor and instrumentation applications.
Available in 8‑lead MSOP, SOIC, TSSOP and 14‑lead packages, the devices operate from 2.7 V to 5 V single supply and are rated for an extended temperature range of –40 °C to +125 °C. The datasheet includes detailed electrical characteristics, absolute maximum ratings, pin configurations, ordering information, and typical performance graphs.
