Overview

The TPA181x is the micro-power and zero-drift amplifier with a maximum 8-μV low-offset voltage. The TPA181x features stable frequency response for the high-precision sensing application that also requires low standby power.

The TPA181x series of devices provide rail-to-rail input and output. These devices have excellent AC performance with 500-kHz bandwidth and 0.3-V/us slew rate while only drawing 55-uA quiescent current per amplifier.

All versions can be operated over the industrial temperature range from −40°C to +125°C.
