TDA7851A中文资料四路BTL输出，支持待机和静音输入以及片段和偏移检测数据手册ST规格书

描述 Description

The TDA7851A is a breakthrough MOSFET technology class AB audio power amplifier, designed for high-power car radio.

The fully complementary P-Channel/N-Channel output structure allows a rail-to-rail output voltage swing. This, combined with high output current and minimized saturation losses, sets new power references in the car-radio field, with unparalleled distortion performance.
