Description

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.
