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 output configuration the high power performance of the TDA7350A 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.
