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
