This datasheet provides details about the OP275 dual bipolar/JFET audio operational amplifier.
The OP275 operational amplifier combines bipolar and JFET input stages to deliver excellent sonic characteristics, low noise (6 nV/√Hz) and very low distortion (0.0006 %). It operates from a single supply of 4.5 V to 22 V and draws only 5 mA.
Available in 8‑lead PDIP and SOIC‑8 packages, the device is specified over an industrial temperature range (‑40 °C to +85 °C) and can drive 600 Ω loads with low distortion. The datasheet includes detailed electrical characteristics, absolute maximum ratings, ordering information, and typical performance graphs.
| Total Harmonic Distortion + Noise | 0.0006 % (3 V rms, 2 kΩ load) |
|---|---|
| Slew Rate | 22 V/µs |
| Gain‑Bandwidth Product | 9 MHz |
| Supply Current | 5 mA |
The offset voltage is guaranteed at 1 mV and is typically less than 200 µV.
The OP275 is offered in 8‑lead PDIP and 8‑lead SOIC (surface‑mount) packages.
It is specified for an industrial temperature range of –40 °C to +85 °C.
