Description
The TPA186xQ series of amplifiers are the newest high-
supply voltage amplifiers with 40-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 6-MHz bandwidth,
5-V/μs slew rate, and low distortion while drawing only
1.4-mA quiescent current per amplifier. The input common-
mode voltage range extends to V−, and the outputs swing
rail-to-rail.
The TPA186xQ has an over-temperature protection feature
to guarantee chip safety. The output of the TPA186xQ
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.
