IRAUDAMP23: 500W x2 @ 20 Ω, ±80 V~±180 V in

Summary

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 systems. This evaluation board demonstrates how to use the IRS2452AM controller IC, implement protection circuits, and design an optimum PCB layout.

Applications

Constant voltage distribution system
Installation system
Paging system

Features
