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.
