TDA7372A - 4 x 6W POWER AMPLIFIER FOR CAR RADIO

The TDA7372A is a new technology class AB quad channels Audio Power Amplifier in Multiwatt15 package designed for car radio applications.

Thanks to the fully complementary PNP/NPN output configuration the TDA7372A delivers a rail to rail voltage swing with no need of boostrap capacitors.

• a St-BY function which shuts down the internal bias generators when the ST-BY input is low. In ST-BY mode the amplifier sinks a small current (in the range of few µAs). When the St-BY pin is high the IC becomes fully operational. A mute function is also provided. This reduces the gain of the input stage to a level effectively eliminating any audio input influence on the output stage when the mute line is low. When the mute line is high the normal input path is restored. The device goes automatic.
