DESCRIPTION
The TDA7350A is a new technology class AB
Audio Power Amplifier in the Multiwatt^® package
APPLICATION CIRCUIT BRIDGE
MULTIWATT 11
ORDERING NUMBER: TDA7350A
designed 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.
