Product Description
MA5332MS , 200W Stereo, Integrated Class D AmplifierDescriptionThe 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 outputsApplications• Multi-channel home theatre system• Studio monitor• Active speaker• Soundbar subwoofer• Marine amplifier• Aftermarket car audio system• General-purpose audio power amplifier
