IR4301MTRPBF

IR4301MTRPBF is an integrated analogue input class D audio amplifier. It integrates PWM controller and digital audio MOSFETs forming a high performance Class D audio amplifier. As a result of fully optimized MOSFETs co-packed with a dedicated controller IC, the IR43X1 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. Typical applications include home theatre systems, docking station audio systems, PC audio systems, musical instruments, karaoke amplifiers, game consoles, powered speaker systems, general purpose audio power amplifiers.
