This document describes the features and characteristics of the OP275 dual bipolar/JFET audio operational amplifier from Analog Devices, including low noise, low distortion, high slew rate, wide bandwidth, low supply current, low offset voltage, and offset current.
The OP275 dual audio operational amplifier combines bipolar and JFET input stages to deliver excellent sonic performance, low noise (6 nV/√Hz at 1 kHz) and very low distortion (0.006 % THD+N). It operates over an extended industrial temperature range (‑40 °C to +85 °C) and is available in 8‑lead PDIP and SOIC packages.
The device features a high slew rate of 22 V/µs, a gain‑bandwidth product of 9 MHz, and can drive 600 Ω loads to 10 V rms while maintaining low distortion. Typical applications include high‑performance audio, active filters, fast amplifiers and integrators.
| THD+Noise (3 V rms, 2 kΩ load) | 0.006 % |
|---|---|
| Supply Current | 5 mA |
