D7377

Silicore 2×30W Dual/Quad Power Amplifier for Car Radio D7377 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 comp ression operation. The fault diagnostics makes it possible to detect mistakes during car radio set assemb ly and wiring in the car.
