4 x 25 W Car Amplifier TDA7381 Circuit


Posted on Feb 4, 2014

The TDA7381 is a class AB audio power amplifier in Flexiwatt25 package designed for car radio applications. You you can also use this circuit for other purposes. Thanks to the fully complementary PNP/NPN output configuration the TDA7381 allows a rail to rail output voltage swing with no need of bootstrap capacitors. The extremely reduced component
