Description

The TDA7388A is a new technology class AB audio power amplifier in Flexiwatt 27 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.
