E-TDA7375AV

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.
