TDA7396 45W/2ohm BRIDGE CAR RADIO AMPLIFIER WITH DIAGNOSTIC FACILITY

The TDA7396 is a BRIDGE class AB audio power amplifier especially intended for car radio High Power applications. The 2Ω power capability together with the possibility to operate either in DIFFERENTIAL INPUT MODE or SINGLE ENDED INPUT MODE makes it suitable for boosters and high end car radio ap- Fi.

TDA7396 Features

* a ST-BY function which shuts down all the internal bias supplies 8 STAND-BY when the ST-BY input is low. In ST-BY mode the amplifier sinks a small current (in the range of few µA). When the ST-BY pin is high the IC becomes fully operational. A resistor (RS) has to be connect between pin 10 and
