TDA7377

DESCRIPTION

The UTC TDA7377 is a class AB car radio amplifier for car

radio, it can work either in dual bridge or quad single ended

configuration. The exclusive fully complementary structure of the

output stage and the internally fixed gain guarantees the highest

possible power performances with few external components. The

on-board clip detector simplifies gain compression operation. The

fault diagnostics makes it possible to detect mistakes during car

radio set assembly and wiring in the car.

FEATURES
