DESCRIPTION

The TDA7393 is a new technology class AB
Audio Power Amplifier in Multiwatt15package de­signed for high end car radio applications.Thanks
to the fully complementary PNP/NPN output con­figuration the high power performances of the
TDA7393 are obtained without bootstrap capaci­tors. The extremely reduced components count
