DESCRIPTION
The TDA7360 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 TDA7360 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.
The device provides a circuit for the detection of
clipping in the output stages. The output, an open
collector, is able to drive systems with automatic
volume control.
This is advanced information on a new product now in development or undergoing evaluation. Details are subject to change without notice.
