TDA7372B Datasheet (ST Microelectronics) - 4 x 6W POWER AMPLIFIER FOR CAR RADIO

TDA7372B, 4 x 6W POWER AMPLIFIER FOR CAR RADIO

The TDA7372B 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 TDA7372B delivers a rail to rail voltage swing with no need of boostrap capacitors.

TDA7372B Features

* a St-BY function which shuts down the internal bias supplies when the STBY 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 stag
