The 8-SOIC package is a common footprint, so layout reuse across projects is straightforward. ## 1W into 8Ω — what it means for the speaker load The 1W x 1 @ 8Ω rating is the headline number for a small speaker driver. That is enough output for a portable Bluetooth speaker or a voice-prompt module in an appliance. The 110mW x 1 @ 32Ω figure covers headphone output — the same amplifier drives both loads, so a single-ended headphone jack and a mono speaker can share the chip with a simple output switch. No external buffer needed. Supply current scales with output; at lower listening levels the quiescent draw stays modest. The shutdown pin lets the system cut power to the amplifier when the audio path is idle, extending battery life in handheld gear. ## Active and RoHS3 compliant — no LTB pressure The LM4875M/NOPB carries an active lifecycle status and is ROHS3 compliant. There is no last-time-buy or end-of-life notice. For a BOM line that needs a proven, simple audio amplifier, this part is a stable choice for both new production and ongoing builds.","metaTitle":"LM4875M/NOPB TI Boomer Class AB Audio Amp, 1W Mono 8-SOIC","metaDescription":"LM4875M/NOPB Texas Instruments Boomer Class AB audio amplifier. 1W into 8Ω mono, 110mW into 32Ω headphones. 2.7-5.5V supply, industrial temp.","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":"Tube","Features":"Depop, Mute, Shutdown, Thermal Protection, Volume Control","Output Type":"1-Channel (Mono) with Mono Headphones","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.7V ~ 5.5V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-SOIC","Max Output Power x Channels @ Load":"1W x 1 @ 8Ohm; 110mW x 1 @ 32Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.56","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.56000","currency":"USD"},{"qty":10,"price":"$2.29500","currency":"USD"},{"qty":25,"price":"$2.16560","currency":"USD"},{"qty":100,"price":"$1.84500","currency":"USD"},{"qty":250,"price":"$1.73240","currency":"USD"},{"qty":500,"price":"$1.51586","currency":"USD"},{"qty":1000,"price":"$1.25599","currency":"USD"},{"qty":2500,"price":"$1.22576","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/5e1d7d6c911dc3177d0a5e97cdec9fdb.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LM4875M/NOPB RoHS compliant?","answer":"Yes, the LM4875M/NOPB is ROHS3 compliant."},{"question":"What is LM4875M/NOPB's listed type?","answer":"The LM4875M/NOPB is a Class AB audio amplifier."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM4875M-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/LM4875M-NOPB when reusing this data.
