As a result of fully optimized MOSFETs co-packed with a dedicated controller IC, the IR43X1operates without mechanical heatsink attached in a typical music playback usage. High voltage ratings and noise immunity in the controller IC ensures reliable operation over various environmental conditions. A small 5x6 mm PQFN package enhances the benefit of smaller size of Class D topology. The IR43x1 are a lead-free, ROHS compliant. Typical Connection Diagram 1. Inverting Amplifier INPUT 2.
