The 48-HTQFP (7x7 mm) package with exposed thermal pad is the standard power-QFP footprint for this power class. ## Package and mounting Rated at 15W per channel into 8Ω, this part drives typical bookshelf or satellite speakers in a stereo pair. The Class D switching topology keeps efficiency high — expect less than 10W dissipation at full output, which the exposed pad on the 48-HTQFP can handle with a decent via-stitch to the ground plane. If your load drops to 4Ω, the output current limit will reduce power; stay with 8Ω for the rated figure. ## Supply rail and control interface I²C control handles volume, mute, and shutdown, plus the depop feature that suppresses turn-on thump. Differential inputs reject ground noise on long signal runs, which matters for board-level routing. Fine for home audio, AV receivers, soundbars, and pro-audio gear that stays indoors. Not rated for automotive cabin or outdoor enclosures where the ambient swings below freezing. ## Rework note on the 48-HTQFP The 48-HTQFP (7x7 mm) has a 0.5 mm pitch — fine for hand rework with a hot-air station if you preheat the board. The exposed thermal pad under the package needs a good solder joint to the ground plane; a missing or cold pad joint will let the thermal protection trip early.","metaTitle":"TAS5719PHPR Class D Stereo Amplifier, 15W x 2 @ 8Ω","metaDescription":"Texas Instruments TAS5719PHPR Class D stereo amplifier, 15W per channel into 8Ω, 48-HTQFP, I²C control, active production.","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":"Depop, Differential Inputs, I²C, Shutdown, Thermal Protection, Volume Control","Output Type":"2-Channel (Stereo) with Stereo Headphones","Mounting Type":"Surface Mount","Package / Case":"48-PowerTQFP","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Operating Temperature":"0°C ~ 85°C (TA)","Supplier Device Package":"48-HTQFP (7x7)","Max Output Power x Channels @ Load":"15W x 2 @ 8Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.45","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.45000","currency":"USD"},{"qty":10,"price":"$5.82500","currency":"USD"},{"qty":25,"price":"$5.55400","currency":"USD"},{"qty":100,"price":"$4.82270","currency":"USD"},{"qty":250,"price":"$4.60592","currency":"USD"},{"qty":500,"price":"$4.19950","currency":"USD"},{"qty":1000,"price":"$3.83400","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/64b1ff47fbc4b821e47abc571c549e0f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the output power of TAS5719PHPR?","answer":"The TAS5719PHPR delivers 15W per channel into an 8Ω load in a stereo configuration."},{"question":"What are alternatives to TAS5719PHPR?","answer":"Within TI's Class D audio amplifier family, parts like the TAS5720 or TAS5731 offer similar output power with different feature sets (e.g., higher channel count or integrated DSP).
