TPA1811

30-V, 500-kHz, High-Precision, Low-Power, Zero-Drift Op Amps

Overview

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

The TPA181x series provides rail-to-rail input and output. The series has excellent AC performance with 500-kHz bandwidth and 0.3-V/μs slew rate while only drawing 55-μA quiescent current per amplifier.

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