LINEAR INTEGRATED CIRCUIT
2 x 30W DUAL/QUAD POWER
AMPLIFIER FOR CAR RADIO
„ 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.
