The IRAUDAMP16 reference design is a two-channel, 70 W/ch (4 Ω/±23 V; no heatsink)/ 130 W/ch (4 Ω/±31 V; with heatsink) half-bridge Class D audio power amplifier.
This reference design demonstrates how to use the IR4302 IC, implement protection circuits, and design an optimum PCB layout using PowIRaudio integrated Class D IC. This reference design does not require additional heatsink or fan cooling for normal operation (one-eighth of continuous rated power).
The reference design provides all the required housekeeping power supplies for ease of use. The two-channel design is scalable for power and the number of channels.
Possible applications include: AV receivers, home theater systems, mini component stereos, powered speakers, subwoofers, musical instrument amplifiers, and car audio amplifiers.
