DESCRIPTION

The TDA7350A is a new technology class AB

Audio Power Amplifier in the Multiwatt

®

package

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.
