TDA7388A

4x42W四桥汽车收音机放大器

Description

The 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.
