STMicroelectronics STA7360
The STA7360 is a class-AB audio power amplifier in the Multiwatt® package.Thanks to the fully complementary PNP/NPN output configuration, the high-power performance of the STA7360 is obtained without bootstrap capacitors. 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.FEATURES
● Very few external components● No boucherot cells

DESCRIPTION
A delayed turn-on mute circuit eliminates audible on/off noise, and a short-circuit protection system prevents spurious intervention with highly inductive loads. Table 1.
