描述 Description

The TP128x is a series of the newest high supply voltage

amplifiers with low offset, low power, and stable highfrequency

response. The series incorporates 3PEAK's

proprietary and patented design techniques to achieve

excellent AC performance with 7-MHz bandwidth, 20-V/μs

slew rate, and low distortion while drawing only 1600

μA of quiescent current per amplifier. The input commonmode

voltage range extends to ?VS, and the outputs

swing rail-to-rail. The TP128x series can be used as plugin

replacements for commercially available op amps to

reduce power, extend input/output range, and improve

performance.

The TP128x has an over-temperature protection to

guarantee chip safety. The outputs of TP128x enter high

impendence when the die temperature reaches around

170°C, and recover the function when the die temperature

is down to around 150°C.
