Description：

The TPA655x is a series of single, dual, and quad RRIOop amps with low offset, low power, and stable highfrequency response. The series incorporates 3PEAK’sproprietary and patented design techniques to achieve 10-MHz bandwidth, 3-V/μs slew rate, and low distortion.The TPA655x op amps have 1-μVPP voltage noise at 0.1Hz to 10 Hz, because the bipolar transistor in the inputstage with low 1/f noise is used as the input stage.Considering the requirements of the low standby powerin some special applications, there is a shutdown functionwhich is TPA6551N with only 0.5-μA shutdown current.
