15W+15W Dual bridge amplifier Designed by using TDA7297 IC

15W+15W Dual bridge amplifier and it is most suitable for low power car audio amplifier.  This amplifier IC accepts wide range of supply voltage from 6V to 18V. It produce good audio output with minimum external components hence board size becomes tiny.

This IC has stand by and mute functions and it can be handled through microprocessor. TDA 7297 contains short circuit protection and thermal overload protection.

Audio amplifier circuit diagram using TDA 7297 is given from its datasheet. In this circuit IN1 and IN2 are represents stereo Audio input and a potentiometer can be connected through these pins to control sound volume level. Connect two separate speakers with right polarity to get good sound output
