Description

The TPA188X series amplifiers are the newest high

supply voltage amplifiers with 15 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, 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 V–, and the outputs swing

rail-to-rail.

The TPA188X has an over-temperature protection

feature to guarantee chip safety. The output of

TPA188X will enter high impendence when the die

temperature reaches around 170°C and will recover

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.
