TDA7377
2 x 30W DUAL/QUAD POWER
AMPLIFIER FOR CAR RADIO
DESCRIPTION
HZIP-15A
LINEAR INTEGRATED CIRCUIT
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.
