TDA7377
tees the highest possible power performances
with extremely reduced component count. The
on-board clip detectorsimplifies gain compression
operation. The fault diagnostics makes it possible
to detect mistakes during car radio set assembly
and wiring in the car.
DESCRIPTION
The TDA7377 is a new technology class AB car
radio amplifier able to work either in DUAL
BRIDGE or QUAD SINGLE ENDED configuration.
The exclusive fully complementary structureof the
output stage and the internally fixed gain guaran-
