It runs on a 2.7 V to 5.5 V supply rail. ## Package and footprint reality The LM4864MM/NOPB comes in an 8-VSSOP package (3.00 mm body width). The surface-mount profile suits automated pick-and-place. ## Shutdown and thermal protection — why they matter The shutdown pin lets a microcontroller or GPIO put the amplifier into a low-power idle state when no audio is needed — a common requirement in battery-operated terminals and portable instruments. Thermal protection prevents the output stage from destructing under a sustained fault or high ambient temperature; the part self-limits rather than failing open or shorted. For a BOM line, this means you can skip an external thermal switch in many designs. ## Lifecycle and sourcing posture The LM4864MM/NOPB is listed as Active with ROHS3 compliance. No end-of-life notice or last-time-buy window is on record. Sourcing is through independent distribution; current availability and pricing are confirmed at quote time against an RFQ.","metaTitle":"LM4864MM/NOPB Class AB Audio Amp, 675 mW mono, 8-VSSOP","metaDescription":"LM4864MM/NOPB from TI's Boomer® series: Class AB audio amplifier, 675 mW into 8 Ω mono, 2.7-5.5 V supply, shutdown & thermal protection, -40 to 85°C, 8-VSSOP.","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":"Tape & Reel (TR); Cut Tape (CT)","Features":"Shutdown, Thermal Protection","Output Type":"1-Channel (Mono)","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.7V ~ 5.5V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-VSSOP","Max Output Power x Channels @ Load":"675mW x 1 @ 8Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.79","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.79000","currency":"USD"},{"qty":10,"price":"$1.61200","currency":"USD"},{"qty":25,"price":"$1.52120","currency":"USD"},{"qty":100,"price":"$1.29600","currency":"USD"},{"qty":250,"price":"$1.21688","currency":"USD"},{"qty":500,"price":"$1.06476","currency":"USD"},{"qty":1000,"price":"$0.88224","currency":"USD"},{"qty":2000,"price":"$0.86100","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/814435f57147a0001d295a722fce8c9f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does LM4864MM/NOPB have thermal protection and shutdown features?","answer":"Yes, it includes both shutdown (for low-power idle) and thermal protection (to prevent damage under fault or high ambient temperature)."},{"question":"What are the recommended alternatives or equivalents for LM4864MM/NOPB?","answer":"The closest pin-compatible alternative in the Boomer® family is the LM4864M/NOPB in an SOIC-8 package — same output power and supply range, different footprint.
