The EVAL_AUDAMP25 MA5332 evaluation board features a 2-channel, 200 W/ch (4 Ω at ±36.5 V; with heatsink) half-bridge class D audio power amplifier for Hi-Fi audio systems. It illustrates the use of the MA5332 IC, protection circuits implementation, and the design of an optimized PCB layout using Infineon integrated Class D IC. Notably, the reference design does not require additional heatsink or fan cooling for normal operation, up to one-eighth of continuous rated power.
