INFINEON MA5342MSXUMA1 Audio Power Amplifier, MERUS, 200W x 2 @ 8Ohm, 400W x 1 @ 16Ohm, D, 2 Channels

MA5342MSXUMA1 is an analogue input, 2x200W Class D amplifier. It provides output power that is equivalent to or greater than monolithic alternatives, while occupying 50% less space and requiring little or no heatsink. This is achieved through the integration of a 2-channel PWM controller, a high voltage gate driver, and 4 low RDS(ON) MOSFET in a multi-chip module (MCM) solution. Similar to its predecessor, the IR43x2M, the MA5342MS includes standard Class D protection features that ensure reliable operation across various environmental conditions. With its small package, the MA5342MS represents a powerful upgrade over the IR43x2M and other monolithic alternatives, delivering high power density and the benefits of heatsink-less operation. The application includes a multi-channel home theatre, studio monitor, active speaker, subwoofer, marine amplifiers, aftermarket car audio, and general-purpose audio power amplifier.
