The IRAUDAMP10 demo board is a reference design which uses only one IC (IRS2052M) to derive appropriate input signals, amplify the audio input, and achieve a two-channel 280 W/ch (4Ω, THD+N=1%) half-bridge Class D audio power amplifier.
The reference design demonstrates how to use the IRS2052M Class D audio controller and gate driver IC, implement protection circuits, and design an optimum PCB layout using IRF6775 DirectFET MOSFETs.
The reference design contains all the required housekeeping power supplies for ease of use. The two-channel design is scalable, for power and number of channels.
Applications include: AV receivers, home theater systems, mini component stereos, powered speakers, sub-woofers, musical Instrument amplifiers, and automotive after-market amplifiers.
