TDA7388 Description

The TDA7388 is an AB-class audio power amplifier in FlexiWatt 25 package designed for high-end automotive radio applications. Based on a fully complementary PNP/NPN configuration, the TDA7388 allows rail-to-rail output voltage to swing without bootstrapping capacitors. A very small number of boundary components allows for very compact collections.
