DESCRIPTION

The STA7360 is a new technology class AB Audio

Power Amplifier in the Multiwatt® package.Thanks to

the fully complementary PNP/NPN output configura-

tion the high power performance of the STA7360 is

obtained without bootstrap capacitors.

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 clip-

ping in the output stages. The output, an open collec-

tor is able to drive systems with automatic volume

control.
