Description

The YD7377 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 structure of the output stage and the internally fixed gain guaran-tees the highest possible power performances with extremely reduced component count. 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.
