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.
