The IRAUDAMP4A reference design is an example of a two-channel 120 W half-bridge Class D audio power amplifier. The reference design will demonstrate how to use the IRS20957, implement protection circuits, and design an optimum PCB layout using the IRF6645 DirectFET MOSFETs.
The IRAUDAMP16 reference design is a two-channel, 70W/ch (4Ω ±23V; no heatsink)/ 130 W/ch (4 Ω/±31 V; with heatsink) half-bridge Class D audio power amplifier.
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 IRAUDAMP21 reference design is a two-channel, 90W/ch (2Ω/±18V; no heatsink)/ 135W/ch (2Ω/±22V; *with heatsink) half-bridge Class D audio power amplifier. This reference design demonstrates how to use the IR4321 IC, implement protection circuits, and design an optimum PCB layout using PowIRaudio integrated Class D IC.
The REF_MA5332BTLSPS reference board is a one BTL channel, 200 W/ch (4 Ω at 40 V) class D audio power amplifier for home audio systems.
