It integrates depop, differential inputs, mute, standby, and short-circuit/thermal protection — a full-featured output stage for active speakers, soundbars, and automotive aftermarket audio where board space and heat dissipation matter. The date-code and lot traceability are verified against STMicro's factory marking standards before shipment. ## Second-source and cross-shop considerations The closest functional sibling is the TDA7492P13TR, also a Class D stereo amplifier but rated 25W per channel into 8Ω — a 5W/channel increase that may require a larger heatsink or supply headroom. The TDA7491HV13TR's 20W rating is a better fit for designs where the 8Ω load is fixed and the thermal budget is tight. No pin-compatible second-source alternate is listed; the TDA7492P13TR shares the same package outline (PowerSSO-36) but verify the pinout for drop-in replacement.","metaTitle":"STMicro TDA7491HV13TR Class D Stereo Amp, 20W x 2 @ 8Ω","metaDescription":"STMicro TDA7491HV13TR Class D audio amplifier, stereo 20W x 2 @ 8Ω, 5-18V supply, -40 to 85°C, PowerSSO-36 EPD.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"Class D","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Depop, Differential Inputs, Mute, Short-Circuit and Thermal Protection, Standby","Output Type":"2-Channel (Stereo)","Mounting Type":"Surface Mount","Package / Case":"36-PowerBFSOP (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"5V ~ 18V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"PowerSSO-36 EPD","Max Output Power x Channels @ Load":"20W x 2 @ 8Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.99","priceTiers":[{"qty":1,"price":"$3.99000","currency":"USD"},{"qty":10,"price":"$3.57900","currency":"USD"},{"qty":25,"price":"$3.38360","currency":"USD"},{"qty":100,"price":"$2.93260","currency":"USD"},{"qty":250,"price":"$2.78220","currency":"USD"},{"qty":500,"price":"$2.49646","currency":"USD"},{"qty":1000,"price":"$2.10545","currency":"USD"},{"qty":2000,"price":"$2.00018","currency":"USD"},{"qty":5000,"price":"$1.92498","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/5644981da9c96c35c5e204b58ee13741.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TDA7491HV13TR/alternatives.json"},"ai":{"faq":[{"question":"What is the output power of the TDA7491HV13TR?","answer":"It delivers 20W per channel into 8Ω loads (stereo, 2-channel).
