Description

The TPA655x series op-amps are single, dual, and quad

RRIO op-amps with low offset, low power, and stable highfrequency response. They incorporate 3PEAK’s proprietary

and patented design techniques to achieve 10-MHz

bandwidth, 3-V/μs slew rate, and low distortion.

The TPA655x series op-amps have 1-μVPP voltage noise

at 0.1 Hz to 10 Hz, because the bipolar transistor in the

input stagewith low 1/f noise is used as the input stage.

Considering the requirement of the low standby power in

some special applications, there is a shutdown function

which is TPA6551N with only 0.5-μA shutdown current.
