LPV821 Datasheet Zero-Drift Amplifier

Manufacturer: Texas Instruments

General Description

The LPV821 is a single-channel, nanopower, zerodrift operational amplifier for “Always ON” sensing applications in wireless and wired equipment where low input offset is required.

With the combination of low initial offset, low offset drift, and 8 kHz of bandwidth from 650 nA of quiescent current, the LPV821 is the industry's lowest power zero-drift amplifier that can be used for end equipment that monitor current consumption, temperature, gas, or strain gauges.

The LPV821 zero-drift operational amplifier uses a proprietary auto-calibration technique to simultaneously provide low offset voltage (10 μV, maximum) and minimal drift over time and temperature.
