Description：

DescriptionThe TPA5571Q and TPA5572Q are the newest zero-driftamplifiers with a maximum 45-μV low-offset voltage, lownoise, and stable high-frequency response. It incorporatesproprietary and patented design techniques to achieveexcellent AC performance with 15-MHz bandwidth, 5-V/μsslew rate, and low distortion while drawing 1-mA quiescentcurrent per amplifier. The input common-mode voltageextends to the power rail, and the output swings rail-to-rail.The amplifier can be used as a plug-in replacement forcommercially available op amps to improve performance.Considering the requirements of the low standby power,there is a shutdown function which is in TPA5571NQ withonly 7.5-μA shutdown current.
