TDA7388A中文资料四路BTL输出功率放大器，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 TDA7388A is a new technology class AB audio power amplifier in Flexiwatt27 package designed for high end car radio applications.

Thanks to the fully complementary PNP/NPN output configuration the TDA7388A allows a rail to rail output voltage swing with no need of bootstrap capacitors. The extremely reduced components count allows very compact sets.

The TDA7388A is also equipped with Clipping detector and Offset detector features.
