Description

The TDA7385 is a new technology class AB Audio Power Amplifier in Flexiwatt 25 package

Thanks to the fully complementary PNP/NPN output configuration the TDA7385 allows a rail to rail output voltage swing with no need of bootstrap capacitors. The extremely reduced components count allows very compactsets.

The on-board clipping detector simplifies gain compression operations. The fault diagnostics makes it possible to detect mistakes during Car-Radio assemblyand wiring in the car.
