TDA7376B Amplifier Description

The TDA7376B is a dual bridge audio amplifier in a Multiwatt 15 package developed for automotive radio applications. The TDA7376B provides a rail-to-rail voltage swing without the use of bootstrap capacitors due to its fully functional PNP/NPN output stage architecture. Differential input pairs ensure strong noise immunity, making the device appropriate for both car radio and car booster applications.
