TDA7379: AUDIO POWER AMPLIFIER

TDA7379: AUDIO POWER AMPLIFIER

The TDA7379 is a new technology class AB audio processor 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 guarantee the highest power performances with extremely reduced component count. The on board clip detector simpli- fies gain compression operation. The fault diagnostic makes it possible to detect mistakes during the set assembly and wiring in the equipment.
