TDA7377

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.
