Description
The TDA7381 is a class AB audio power amplifier
in Flexiwatt25 package designed for car radio
applications. 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 components count allows
very compact sets. The on-board clipping
detector simplifies gain compression operations.
The fault diagnostics makes it possible to detect
mistakes during Car- Radio assembly and wiring
in the car
