IRAUDAMP23
Overview
Reference design board – 2-channel 500 W/ch half-bridge class D audio power amplifier featuring IRS2452M controller IC
The IRAUDAMP23 evaluation board is a two-channel, 500 W/ch (100 Vrms, 20 Ω at ±148.3 V) half-bridge Class D audio power amplifier for high impedance distribution system. This evaluation board demonstrates how to use the IRS2452AM controller IC, implement protection circuits, and design an optimum PCB layout.
