DESCRIPTION

The TDA7393 is a new technology class AB

Audio Power Amplifier in Multiwatt15 package de-

signed for high end car radio applications. Thanks

to the fully complementary PNP/NPN output con-

figuration the high power performances of the

TDA7393 are obtained without bootstrap capaci-

tors. The extremely reduced components count
