TPA1831

概述

The TPA183x is a series of micro-power, zero-drift amplifiers with a maximum 18-μV low-offset voltage and stable frequency response for high-precision sensing applications that also require low standby power.

The TPA183x series provides rail-to-rail input and output. The series has excellent AC performance with 1.1-MHz bandwidth and 0.7-V/μs slew rate, while only drawing 140-μA quiescent current per amplifier.

The TPA183x series is operated over the industrial temperature range from −40°C to +125°C.
