TEXAS INSTRUMENTS OPA227 OPA2227 OPA4227 OPA228 OPA2228 OPA4228 High Precision Low Noise OPERATIONAL AMPLIFIERS handbook
The OPA227 and OPA228 families are low‑noise, high‑precision operational amplifiers offered in single, dual and quad packages. They provide wide bandwidth (8 MHz for OPA227, 33 MHz for OPA228) and low offset voltage, making them suitable for audio, data‑acquisition, telecom and instrumentation applications.
The devices operate from a wide supply range of +2.5 V to +18 V, feature low input bias current (10 nA max) and high common‑mode rejection (138 dB). Detailed electrical specifications, absolute maximum ratings, mechanical dimensions and typical performance curves are provided in this datasheet.
