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.
