Integrated features — depop circuitry, shutdown, thermal protection, and volume control — reduce external component count and simplify the audio path. ## 105 mW per channel — what it means for headphone selection With 105 mW per channel into 16 Ω, the LM4811MMX/NOPB can drive typical portable headphones (16 Ω to 32 Ω) to adequate listening levels without external gain stages. For lower-impedance loads (e.g., 8 Ω earbuds), the output current limit will reduce available power; check the load line against your target SPL. The 2 V minimum supply ensures operation from a nearly depleted Li-ion cell (3.0 V nominal, down to 2.7 V cutoff) without dropout. ## Active production — no obsolescence watch needed ROHS3 compliant. ## 10-VSSOP package — footprint and layout notes The small package suits space-constrained PCBs in portable products. Supply decoupling with 1 µF ceramic close to the supply pin is recommended; the shutdown pin can be tied to a GPIO for power-save control.","metaTitle":"LM4811MMX/NOPB Class AB Stereo Headphone Amp, 105mW","metaDescription":"Texas Instruments LM4811MMX/NOPB Boomer® Class AB stereo headphone amplifier, 105mW per channel into 16Ω, 2V-5.5V supply, -40°C to 85°C, 10-VSSOP.","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, Volume Control","Output Type":"Headphones, 2-Channel (Stereo)","Mounting Type":"Surface Mount","Package / Case":"10-TFSOP, 10-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2V ~ 5.5V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"10-VSSOP","Max Output Power x Channels @ Load":"105mW x 2 @ 16Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.42","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.42000","currency":"USD"},{"qty":10,"price":"$1.27000","currency":"USD"},{"qty":25,"price":"$1.20520","currency":"USD"},{"qty":100,"price":"$0.98980","currency":"USD"},{"qty":250,"price":"$0.92528","currency":"USD"},{"qty":500,"price":"$0.81768","currency":"USD"},{"qty":1000,"price":"$0.64554","currency":"USD"},{"qty":3500,"price":"$0.47100","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8a8d2a5e6e5e67d19815093d4de878a0.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can LM4811MMX/NOPB operate at 3.3V?","answer":"At 3.3 V the output power will be slightly lower than at 5 V, but still sufficient for most portable headphone loads."},{"question":"What is the output power of LM4811MMX/NOPB per channel?","answer":"The LM4811MMX/NOPB delivers 105 mW per channel into a 16 Ω load.
