Description

The TPA186xQ is a series of the newest high-supplyvoltage

amplifiers with 40-μV low offset, low noise, and

stable high-frequency response. The TPA186xQ series

incorporates 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

common-mode input voltage range extends to V−, and the

outputs swing rail-to-rail.

The TPA186xQ series 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 TPA186xQ series has a very small

power temperature coefficient, which is beneficial for

temperature-sensitive applications
