DESCRIPTIONS：
The D7377 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 guarantees
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.
