It operates from a 12 V to 30 V supply rail and is packaged in a 44-HTSSOP with an exposed thermal pad for heat sinking. The part includes depop circuitry to suppress turn-on clicks and integrated short-circuit and thermal protection. Typical applications include powered speakers, soundbars, home theater systems, and commercial audio installations where high efficiency and compact PCB area are priorities. ## Output power and supply rail — sizing the BOM The 115 W x 2 into 2 Ω rating sets the transformer and bulk capacitor requirements for the power supply. At 230 W bridged into 4 Ω, the single-channel output can drive a subwoofer or a high-power mono speaker. The 12 V to 30 V supply range means the same board can be reused across different system voltage rails — a 24 V industrial supply or a 19 V laptop brick both work, but the output power scales with the rail. For a given load impedance, lower supply voltage reduces headroom; at 12 V into 8 Ω the output drops to roughly 30 W per channel (typical for a desktop speaker). ## Package and thermal management Without adequate thermal coupling, the junction temperature rises quickly under continuous high-power output, especially into 2 Ω loads where dissipation is highest.","metaTitle":"TPA3245DDV Class D Stereo Amp, 115W x 2 @ 2Ω","metaDescription":"Texas Instruments TPA3245DDV PurePath™ Class D audio amplifier, 115W x 2 into 2Ω, 12V–30V supply, 44-HTSSOP.","metaKeywords":null},"attributes":{"series":"PurePath™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Type":"Class D","Series":"PurePath™","Package":"Tube","Features":"Depop, Short-Circuit and Thermal Protection","Output Type":"2-Channel (Stereo)","Mounting Type":"Surface Mount","Package / Case":"44-TSSOP (0.244\\\", 6.20mm Width) Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Supply":"12V ~ 30V","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"44-HTSSOP","Max Output Power x Channels @ Load":"115W x 2 @ 2Ohm, 230W x 1 @ 4Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.47","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.47000","currency":"USD"},{"qty":10,"price":"$7.65300","currency":"USD"},{"qty":25,"price":"$7.29680","currency":"USD"},{"qty":100,"price":"$6.33590","currency":"USD"},{"qty":250,"price":"$6.05112","currency":"USD"},{"qty":500,"price":"$5.51720","currency":"USD"},{"qty":1000,"price":"$5.03700","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/5a7ef16be205b1cae79d6f9454795750.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between TPA3245DDV and TPA3245DDVR?","answer":"The TPA3245DDV and TPA3245DDVR are electrically identical.
