Description

The TDA7375AV is a technology class AB car

radio amplifier able to work either in dual bridge or

quad single ended configuration.

The exclusive fully complementary structure of

the output stage and the internally fixed gain

guarantee the highest possible power

performances with extremely reduced component

count.

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
