Product Summary

The TDA7377 is a new technology class AB car radio amplifier. The TDA7377 is 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 TDA7377 gains compression operation. The fault diagnostics makes it possible to detect mistakes during car radio set assembly and wiring in the car.
