Two-channel Power Amplifier Board TDA7377 

The TDA7377 is a new technology class AB car radio amplifier able to works in DUAL BRIDGE configuration. The exclusive fully complementary structure of the output stage and the internally fixed gain guarantees the highest possible power performances with an extremely reduced component count. The onboard clip detector simplifies gain compression operation.
