Description：

The TPA181x is a series of micro-power and zero-driftamplifiers with a maximum 8-μV low-offset voltage. TheTPA181x series features stable frequency response for thehigh-precision sensing application that also requires lowstandby power.The TPA181x series provides rail-to-rail input and output.The series has excellent AC performance with 500-kHzbandwidth and 0.3-V/μs slew rate while only drawing 55-μA quiescent current per amplifier.All versions are operated over the industrial temperaturerange from −40°C to +125°C.
