Integrated Class D Audio Amplifier ICs

High power efficiency and density in small packages

MERUS™ integrated class D audio amplifier solutions enable customers to maximize audio performance and power efficiency, while providing the highest degree of design freedom for innovative industrial product designs. The integrated audio ICs are available in compact and thermally efficient PQFN packages which eliminate the need for heatsinks.

With the revolutionary multi-level amplifier technology, Infineon is leading the industry in terms of  power efficiency. The monolithic fully integrated multi-level class D audio amplifier ICs allow filter-less heatsink free implementation and give designers enhanced flexibility to optimize audio systems for performance, size and cost to meet critical design objectives in today’s and tomorrow’s audio applications.

The integrated class D audio amplifier multi-chip module (MCM) family of devices integrates PWM controller and digital audio power MOSFETs in a single package to offer a highly power efficient, compact solution that reduces component count, eliminates the need for heatsinks and shrinks PCB size by up to 70%.
