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
