This document introduces the Analog Devices OP471 monolithic quad operational amplifier, which features low noise, high speed, and high gain bandwidth.
The OP471 is a monolithic quad op‑amp offering excellent speed (8 V/µs typical) and very low voltage noise (11 nV/√Hz at 1 kHz). It features low input offset voltage (<0.8 mV), low offset drift, high CMRR (>105 dB) and good PSRR, making it suitable for low‑noise instrumentation, active filters and buffer applications.
The datasheet provides detailed electrical specifications, pin configurations for 14‑lead DIP, 14‑lead plastic DIP and 16‑lead SOIC packages, and extensive performance graphs such as frequency response, noise versus source resistance, and slew‑rate versus temperature. Application notes describe noise measurement methods, capacitive‑load driving techniques, and example low‑phase‑error amplifier circuits.
