That power level puts it in the mid-power bracket — enough to drive a pair of bookshelf speakers in a soundbar, a powered bookshelf monitor, or a multi-room audio zone, without the thermal management headache of a linear Class AB stage. The Class D architecture means most of the heat stays in the load, not the package, which is why a 40-LFCSP-WQ (6x6) exposed-pad package can handle this output. The 4.5 V to 16 V supply range covers the common audio rails: a 5 V USB bus, a 12 V automotive battery line (with cranking margin), or a regulated 15 V supply from a set-top box or active speaker PSU. ## Package and thermal — the exposed pad is not optional At 31.76 W output, the Class D efficiency keeps junction temperatures manageable, but without that pad connection the part will hit thermal shutdown under sustained high-level playback. The 6x6 mm footprint is compact enough for a two-layer board if the ground plane is solid underneath.","metaTitle":"SSM3582ACPZ-R7 Class D Audio Amp, 31.76W x 2 @ 4Ω","metaDescription":"ADI SSM3582ACPZ-R7 stereo Class D amplifier, 31.76W per channel into 4Ω, 4.5V-16V supply, -40°C to 85°C, 40-LFCSP-WQ.

The only difference is the packaging medium: -R7 ships in Tape & Reel, while SSM3582ACPZ ships in Tray. Both are the same die, same 31.76 W output, same 40-LFCSP-WQ package, same supply range. If your pick-and-place line is set up for reels, the -R7 is the correct order code; if you need tray for prototyping or low-volume hand assembly, order the SSM3582ACPZ."},{"question":"What is the maximum output power per channel of SSM3582ACPZ-R7?","answer":"31.76 W per channel into a 4 Ω load, with both channels driven. That figure assumes the supply voltage is within the 4.5 V to 16 V range and the load is purely resistive. Real-world speaker impedance dips below 4 Ω at certain frequencies, which will increase current demand and may trigger the over-current protection — the 4 Ω rating is the design target, not a hard limit."},{"question":"Is SSM3582ACPZ-R7 lead-free?","answer":"Yes — it is ROHS3 compliant, which means it is lead-free and also free of the other restricted substances under the ROHS directive. No special handling beyond standard MSL precautions is needed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/SSM3582ACPZ-R7","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/SSM3582ACPZ-R7 when reusing this data.
