EVAL_AUDAMP25

概要

Reference design/Evaluation board - 200 W / 4 Ohms x 2-channel class D audio power amplifier featuring MA5332

The EVAL_AUDAMP25 MA5332 evaluation board is 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. 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 continuous rated power).
