The Class AB topology keeps crossover distortion low while maintaining reasonable efficiency for a linear stage. ## Key features for the BOM decision Built-in Depop circuitry suppresses power-up and shutdown transients that would otherwise thump the headphones. A dedicated Shutdown pin lets a system controller cut supply current to near zero when audio is idle. Thermal Protection prevents die damage under sustained overload or a shorted output — useful in a field-replaceable module where the end user might plug in mismatched headphones. ## Sourcing and lifecycle reality ROHS3 compliant, so it passes into EU and RoHS-restricted markets without exemption paperwork.","metaTitle":"Texas Instruments LM4809MMX/NOPB Class AB Stereo Headphone","metaDescription":"Texas Instruments LM4809MMX/NOPB Boomer® Class AB stereo headphone amplifier, 105mW per channel into 16Ω, 2V-5.5V supply, 8-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","Output Type":"Headphones, 2-Channel (Stereo)","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP, 8-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":"8-VSSOP","Max Output Power x Channels @ Load":"105mW x 2 @ 16Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.57","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.57000","currency":"USD"},{"qty":10,"price":"$1.40400","currency":"USD"},{"qty":25,"price":"$1.33280","currency":"USD"},{"qty":100,"price":"$1.09470","currency":"USD"},{"qty":250,"price":"$1.02328","currency":"USD"},{"qty":500,"price":"$0.90428","currency":"USD"},{"qty":1000,"price":"$0.71391","currency":"USD"},{"qty":3500,"price":"$0.52050","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c8aa6d9287f2b55c40e33ae52d9d8fb5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can LM4809MMX be used with a 3.3V supply?","answer":"Yes.
