TDA7379

Description

A brand-new class AB audio processor amplifier, the TDA7379 may operate in either a DUAL BRIDGE or QUAD SINGLE ENDED mode.

The output stage's unique fully complementary structure and internally fixed gain ensure the highest power performances with a remarkably low component count. The gain compression process is made simpler by the onboard clip detector. Errors made during set assembly and equipment wiring can be found using the fault diagnostic.
