As a result of fully optimized MOSFETs co-packed with a dedicated controller IC, the IR43X2 operates 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 7x7 mm PQFN package enhances the benefit of smaller size of Class D topology. The IR43X2 series is a lead-free, ROHS compliant. Typical Connection Diagram 1. Inverting Amplifier 2.
