The OP270 is a high performance, monolithic, dual operational amplifier with exceptionally low voltage offset, drift, extremely high gain, outstanding CMR, 2.4 V/μs slew rate, and 5 MHz typical gain bandwidth product.
The OP270 is a high‑performance, dual operational amplifier featuring very low noise density (5 nV/V·Hz at 1 kHz), excellent input offset voltage (75 pV max) and low offset drift (1 pV/°C). It offers a high gain of 1500 V/mV, a gain‑bandwidth product of 5 MHz, a slew rate of 2.4 V/µs, and an outstanding common‑mode rejection of 106 dB. The device is supplied in industry‑standard 8‑lead DIP, CERDIP, PDIP and 16‑lead SOIC packages and is pin‑compatible with several legacy op‑amps.
The datasheet provides detailed electrical specifications, absolute maximum ratings, typical performance curves, and an ordering guide for the various package options. It also includes functional block diagrams and application notes for low‑noise instrumentation, dual buffers, and active filters.
