Overview

The TPA188x is a series of the newest high-supply voltage amplifiers with 15-μV low offset, low noise, and stable high-frequency response. The TPA188x series incorporates proprietary and patented design techniques of 3PEAK to achieve excellent AC performance with 12-MHz bandwidth, 12-V/μs slew rate, and low distortion while drawing only 2000 μA of quiescent current per amplifier. The input common-mode voltage range extends to –VS, and the output swings rail-to-rail.

The TPA188x amplifiers have an over-temperature protection to guarantee chip safety. The outputs of the TPA188x series 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. These products have a very small power temperature coefficient, which is helpful for temperaturesensitive applications.
