The IRAUDAMP7D reference design is a two-channel Class D audio power amplifier that features outputpower scalability. The IRAUDAMP7D offers selectable half-bridge (stereo) and full-bridge (bridged) modes.This reference design demonstrates how to use the IRS2092 Class D audio driver IC, along with IR’s digitalaudio dual MOSFETs, such as IRFI4024H-117P, IRFI4019H-117P, IRFI4212H-117P and IRFI4020H-117P,on a single layer PCB. The design shows how to implement peripheral circuits on an optimum PCB layoutusing a single sided board.
