OPA2227UE4

Instrumentation, Op Amps, Buffer Amps Overview

The OPA2227UE4 is a dual-channel, precision operational amplifier manufactured by Texas Instruments. It features an 8-SOIC surface-mount package and operates within a supply voltage range of 5 V to 36 V (±2.5 V to ±18 V). Key electrical parameters include a gain-bandwidth product of 8 MHz, a slew rate of 2.3 V/µs, and a maximum input offset voltage of 75 µV. The device draws 3.7 mA of operating current per channel and provides a 45 mA output current capability. It exhibits low noise characteristics with 3 nV/√Hz voltage noise density and 400 fA/√Hz current noise density. The unit supports rail-to-rail input and output operation and functions reliably across a temperature range of -40°C to +85°C.
