Introduction
The IRAUDAMP8 Demo board is a reference design which uses only one IC (IRS2093M) to derive
appropriate input signals, amplify the audio input, and achieve a four-channel 120 W/ch (4Ω) half-bridge
Class D audio power amplifier. The reference design demonstrates how to use the IRS2093M Class D audio
controller and gate driver IC, implement protection circuits, and design an optimum PCB layout using
IRF6665 DirectFET MOSFETs. The reference design contains all the required housekeeping power supplies
for ease of use. The four-channel design is scalable, for power and number of channels.
