The Class D architecture keeps efficiency high enough that a small PCB copper area handles the heat — no separate heatsink needed for typical music signals. If your design lives inside a sealed enclosure that hits 85°C ambient, the 3.24W output assumes adequate PCB thermal relief — the DSBGA's thermal path is through the solder balls to the board, so a solid ground-plane connection under the package matters. ## Integrated protection and shutdown — what it saves you Differential inputs reject ground noise between the audio source and the amp — useful when the codec or DAC shares a long ground trace. Short-circuit and thermal protection mean the part survives a speaker-wire short or a stalled airflow condition without latching up or burning. The shutdown pin lets a GPIO or power-management IC cut the 24 mA quiescent draw to near zero when audio is idle, which stretches battery life in always-on listening devices.","metaTitle":"TPA2037D1YFFT Class D Audio Amp, 3.24W Mono, 9-DSBGA","metaDescription":"Texas Instruments TPA2037D1YFFT Class D audio amplifier, 3.24W into 4Ω mono, 2.5-5.5V supply, -40°C to 85°C, 9-DSBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Type":"Class D","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Differential Inputs, Short-Circuit and Thermal Protection, Shutdown","Output Type":"1-Channel (Mono)","Mounting Type":"Surface Mount","Package / Case":"9-UFBGA, DSBGA","lifecycle_stage":"eol_hot","Voltage - Supply":"2.5V ~ 5.5V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"9-DSBGA","Max Output Power x Channels @ Load":"3.24W x 1 @ 4Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.52","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.52000","currency":"USD"},{"qty":10,"price":"$1.35700","currency":"USD"},{"qty":25,"price":"$1.28800","currency":"USD"},{"qty":100,"price":"$1.05810","currency":"USD"},{"qty":250,"price":"$0.98908","currency":"USD"},{"qty":500,"price":"$0.87408","currency":"USD"},{"qty":1250,"price":"$0.69006","currency":"USD"},{"qty":2500,"price":"$0.65100","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/cc421dd86334b3bb3ead0f7064bfbd4e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the TPA2037D1YFFT compatible with 3.3V logic?","answer":"Yes.
