TPA1862

概述

The TPA186x is a series of the newest high-supplyvoltage amplifiers with 30-μV low offset, low noise, and stable high-frequency response. The TPA186x 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 TPA186x series has an over-temperature protection feature to guarantee chip safety. The output of the TPA186x 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 TPA186x series has a very small power temperature coefficient, which is beneficial for temperature-sensitive applications.
