MERUS™ 2-channel analog input class D audio multichip module optimized for high-impedance speakers The MA5342MS is optimized for 4-16 Ω speaker impedances. It offers the same or higher output power than monolithic alternatives without heatsink and 50% less footprint. This MCM solution integrates 2 channel PWM controller, high voltage gate driver, and 4 low RDS(ON) MOSFETs. It includes standard class D protection features for reliable operation over various environmental conditions. MA5342MS has the same 7x7 mm PG- IQFN-42 package as MA5332MS.
