DESCRIPTION
The TDA7375 is a new technology class AB car
radio amplifier able to work either in DUAL
BRIDGEor QUADSINGLEENDED configuration.
The exclusive fully complementarystructureof the
output stage and the internally fixed gain guaran-
tees the highest possible power performances
with extremely reduced component count. The
on-boardclip detectorsimplifies gain compression
operation. The fault diagnostics makes it possible
to detect mistakes during car radio set assembly
and wiring in thecar.
