描述 Description

The TPA188xQ series of amplifiers are the newest high-supply voltage amplifiers with 50-μV low offset, low noise, and stable high-frequency response. They incorporate 3PEAK’s proprietary and patented design techniques to achieve excellent AC performance with 12-MHz bandwidth, 10-V/μs slew rate, and low distortion while drawing only 2-mA quiescent current per amplifier. The input common-mode voltage range extends to V?, and the outputs swing rail-to-rail.

The TPA188xQ has an over-temperature protection feature to guarantee chip safety. The output of the TPA188xQ enters high impendence when the die temperature reaches around 170°C and recovers the function when the die temperature is down to around 150°C. The product has a very small power temperature coefficient, which is helpful for temperature-sensitive applications.
