MA5332MSXUMA1 200 W stereo integrated Class D amplifier, 2-channel, QFN-42

MA5332MS , 200W Stereo, Integrated Class D Amplifier

Description The MA5332MS offers the same or higher output power than monolithic alternatives without heatsink and 50% less footprint. This MCM (multi-chip module) solution integrates 2 channel PWM controller, high voltage gate driver, and 4 low RDS(ON) MOSFETs. Like its predecessor, IR43x2M, it includes standard Class D protection features for reliable operation over various environmental conditions. As a powerful upgrade to IR43x2M and other monolithic solutions, MA5332MS’ 7x7 mm PG- IQFN-42 package showcases the benefit of small footprint, high power density, and heatsink-less operation.

Features - 2 channel analog input Class D audio amplifier in a small 7x7mm package - Very low RDS(ON) at 24.4 mOhm typical, enabling heatsink-less operation at 2x100W at 4Ohm - 95% efficiency Class D at 2x100W at 4Ohm - Split or single power supply capable - Differential or single-ended input - Multiple configuration options: 2xSE, BTL, PSE (Parallel Single-Ended) - Over-current, over-temperature and under-voltage protections with self-reset feature - Start/stop click noise reduction - Clip and Fault reporting outputs

Applications - Multi-channel home theatre system - Studio monitor - Active speaker - Soundbar subwoofer - Marine amplifier - Aftermarket car audio system - General-purpose audio power amplifier
