It operates from a 10 V to 20 V supply rail, making it suitable for a range of consumer and professional audio applications where a single supply powers the output stage. Housed in a 40-lead VFQFN with an exposed pad (PG-VQFN-40), the package is designed for surface-mount assembly and requires a thermal land on the PCB to dissipate heat from the output stage. The exposed pad must be soldered to a copper plane for effective thermal management, especially when driving continuous power near the 74 W limit. ## Output power and load configuration The amplifier is rated for 37 W x 2 into 4 Ω in stereo mode, and 74 W x 1 into 2 Ω in bridged mono mode. The 2 Ω mono rating means the output stage is designed to drive low-impedance loads, which is common in subwoofer or high-current applications. The supply voltage range of 10 V to 20 V means the actual output power scales with the rail voltage — lower supply voltage reduces headroom and maximum output before clipping. Operating temperature is rated from -25°C to 85°C ambient, which covers most indoor and automotive cabin environments but not extended industrial or under-hood ranges. The Class D topology keeps efficiency high — typically above 85% at full power — which reduces the heat sink requirement compared to a linear amplifier of the same output. ## Active production and compliance The part is supplied in Tape & Reel (TR) packaging, with Cut Tape (CT) options available for prototyping or low-volume builds. The PG-VQFN-40 package is MSL (Moisture Sensitivity Level) rated per JEDEC standards — the specific level should be confirmed from the Infineon datasheet for proper bake and handling before reflow.","metaTitle":"Infineon MA2304DNSXUMA1 Class D Audio Amp, 2x37W, PG-VQFN-40","metaDescription":"Infineon MA2304DNSXUMA1 Class D audio amplifier, 2x37W into 4Ω stereo or 74W mono into 2Ω.
