The OP27 is a low noise, precision operational amplifier that combines the low offset and drift of the OP07 with both high speed and low noise. It is ideal for precision instrumentation applications.
The OP27 precision operational amplifier combines low offset and drift with high speed and low noise, making it suitable for precision instrumentation and professional audio applications. It offers a typical input offset voltage of 25 µV, low input bias current of 10 nA, and a slew rate of 2.8 V/µs.
Key features include an 8 MHz gain‑bandwidth product, 126 dB CMRR at VCM +11 V, and a guaranteed output swing of +10 V into 600 Ω. The datasheet provides pin configurations for multiple package types, absolute maximum ratings, typical performance curves, and an ordering guide for various temperature‑range variants.
