The OP777/OP727/OP747 family are precision single‑, dual‑ and quad‑channel rail‑to‑rail output operational amplifiers from Analog Devices. They feature micropower operation, low offset voltage, low input bias current, and can operate from a single 3 V supply up to 30 V or dual ±15 V supplies.
The devices are specified for industrial temperature operation (‑40 °C to +85 °C) and are offered in various surface‑mount packages such as MSOP, SOIC, TSSOP, and narrow‑body variants. Detailed electrical characteristics, absolute maximum ratings, and typical performance curves are provided for design reference.
