Shutdown pin lets a GPIO or power-management IC pull the amplifier into a low-current state when audio is idle — useful for extending standby time in portable gear. Thermal protection cycles the output if the die exceeds safe junction temperature, so a stalled speaker or shorted output won't permanently damage the part. ## Lifecycle and compliance — still in active production Texas Instruments lists the LM4879ITLX/NOPB as Active with no last-time-buy notice. ROHS3 compliant, so it passes the EU RoHS exemption list without lead in the solder balls. No known PCN or EOL window on this Boomer® line as of the latest TI product bulletin. For BOM freeze or long-life designs, the active status means you can qualify it for production without worrying about a sudden discontinuation.","metaTitle":"LM4879ITLX/NOPB TI Boomer Class AB Audio Amp, 1.1W Mono","metaDescription":"LM4879ITLX/NOPB Texas Instruments Boomer Class AB audio amplifier, 1.1W mono output into 8Ω, 2.2V-5.5V supply, 9-DSBGA package.","metaKeywords":null},"attributes":{"series":"Boomer®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Type":"Class AB","Series":"Boomer®","Package":"Bulk","Features":"Depop, Shutdown, Thermal Protection","Output Type":"1-Channel (Mono)","Mounting Type":"Surface Mount","Package / Case":"9-WFBGA","lifecycle_stage":"eol_hot","Voltage - Supply":"2.2V ~ 5.5V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"9-DSBGA","Max Output Power x Channels @ Load":"1.1W x 1 @ 8Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.73","stockQuantity":0,"priceTiers":[{"qty":413,"price":"$0.73000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d80148b235fc6b115a887d5ab11f8706.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to LM4879ITLX/NOPB?","answer":"Within the TI Boomer® family, the LM4879 in a different package variant (e.g., SOIC-8 or MSOP-8) is functionally identical but not pin-compatible due to the BGA footprint. For a drop-in replacement, the LM4879ITLX/NOPB itself is the only 9-DSBGA option; no second-source BGA part is listed. If the board can accommodate a larger package, the LM4879 in an 8-pin SOIC is a common alternative with the same 1.1W output and supply range."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM4879ITLX-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/LM4879ITLX-NOPB when reusing this data.
