That power level suits portable speakers, headphone drivers, and line-output stages in battery-powered gear where a small 8-WSON package keeps board area tight. The 2.2V to 5.5V supply range means it runs directly from a single Li-ion cell or a 3.3V/5V regulated rail without a boost converter — one less inductor on the BOM. ## Industrial temperature grade and environment The shutdown pin and thermal protection give a safety net if the amplifier is driven into clipping on a hot day — the die pulls back before damage, not after. The NOPB suffix confirms lead-free (ROHS3) — no separate Pb-free qualification step needed.","metaTitle":"LM4879SD/NOPB Class AB Audio Amp, 1.1W Mono, 8-WSON","metaDescription":"Texas Instruments LM4879SD/NOPB Boomer® Class AB audio amplifier, 1.1W mono output into 8Ω, 2.2V–5.5V supply, industrial temp -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"Boomer®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Type":"Class AB","Series":"Boomer®","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Depop, Shutdown, Thermal Protection","Output Type":"1-Channel (Mono)","Mounting Type":"Surface Mount","Package / Case":"8-WDFN Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Supply":"2.2V ~ 5.5V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-WSON (4x4)","Max Output Power x Channels @ Load":"1.1W x 1 @ 8Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.68","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.68000","currency":"USD"},{"qty":10,"price":"$1.50100","currency":"USD"},{"qty":25,"price":"$1.42480","currency":"USD"},{"qty":100,"price":"$1.17020","currency":"USD"},{"qty":250,"price":"$1.09392","currency":"USD"},{"qty":500,"price":"$0.96672","currency":"USD"},{"qty":1000,"price":"$0.76320","currency":"USD"},{"qty":2000,"price":"$0.72000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f8602135303d15285dd697b19dcff304.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LM4879SD/NOPB lead-free?","answer":"Yes, the NOPB suffix indicates ROHS3 compliance — no lead, no RoHS-exempt substances."},{"question":"What is the output power of LM4879SD/NOPB?","answer":"It delivers 1.1W into an 8Ω load from a single mono channel."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM4879SD-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM4879SD-NOPB when reusing this data.
