dio Power Amplifier in the Multiwatt® package de-
signed for car radio applications.
Thanks to the fully complementary PNP/NPN out-
put configuration the high power performance of
the TDA7350A is obtained without bootstrap ca-
pacitors.
A delayed turn-on mute circuit eliminates audible
on/off noise, and a novel short circuit protection
system prevents spurious intervention with highly
inductive loads.
