EVAL_AUDAMP25 evaluation board

The EVAL_AUDAMP25 MA5332 evaluation board is a two-

channel, 200 W/ch (4 Ω at ±36.5 V; with heatsink) half-

bridge class D audio power amplifier for Hi-Fi audio sys-

tems. This evaluation board demonstrates how to use

MA5332 IC, implement protection circuits, and design an

optimum PCB layout using Infineon integrated Class D IC.

This reference design does not require additional heatsink

or fan cooling for normal operation (one-eighth of continu-

ous rated power).
