OPA378 - Precision OPERATIONAL AMPLIFIER

Download the OPA378 datasheet PDF. This datasheet also covers the OPA2378 variant, as both devices belong to the same precision operational amplifier family and are provided as variant models within a single manufacturer datasheet.

General Description

The OPA378 and OPA2378 represent a new generation of Zerø-Drift, microPOWER™ operational amplifiers that use a proprietary auto-calibration technique to provide minimal input offset voltage (20μV) and offset voltage drift (0.1μV/°C).

Key Features

  • 1.
  • 23 LOW NOISE.
  • 0.4μVPP, 0.1Hz to 10Hz.
  • 20nV/√Hz at 1kHz.
  • ZERØ-DRIFT SERIES.
  • LOW OFFSET.
