The 20 µVrms noise over 10 Hz to 10 kHz is low enough for a 12-bit ADC reference rail. Existing production runs still source through independent distribution, but new BOMs should evaluate the active LM4041 variants in the same SOT-23-3 footprint. That covers outdoor telecom cabinets, engine-bay electronics, and factory-floor sensor modules without a derating step. ## Shunt topology — 68 µA cathode current, 12 mA output As a shunt reference, it sinks current from the supply through a series resistor. Maximum output current is 12 mA, enough to drive a handful of op-amp inputs or a low-power ADC reference input without a buffer. ## SOT-23-3 — small footprint, Tape & Reel delivery Housed in the SOT-23-3 (TO-236-3 / SC-59) surface-mount package, it occupies roughly 3 mm × 3 mm of board area. Supplied in Tape & Reel, it suits automated pick-and-place assembly for medium-to-high volume production.","metaTitle":"LM4041CEM3X-ADJ Shunt Voltage Reference","metaDescription":"LM4041CEM3X-ADJ precision adjustable shunt reference, 1.233V to 10V output, ±0.5% tolerance, 20µVrms noise, -40°C to 125°C, SOT-23-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Tolerance":"±0.5%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Not For New Designs","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"12 mA","Current - Supply":"-","Current - Cathode":"68 µA","Base Product Number":"LM4041","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"20µVrms","Operating Temperature":"-40°C~125°C(TA)","Voltage - Output (Max)":"10 V","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"100ppm/°C","Voltage - Output (Min/Fixed)":"1.233V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6450","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d2855eaed3a119e1ade8ae46dfbd1dff.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4041CEM3X-ADJ/alternatives.json"},"ai":{"faq":[{"question":"Is the LM4041CEM3X-ADJ obsolete?","answer":"It is not yet formally discontinued, but it is not recommended for new designs."},{"question":"What is the tolerance of LM4041CEM3X-ADJ?","answer":"Initial output tolerance is ±0.5 %."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM4041CEM3X-ADJ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM4041CEM3X-ADJ when reusing this data.
