The output noise is specified at 180 µVrms over a 10 Hz to 10 kHz bandwidth — adequate for 12-bit systems but worth budgeting for in 16-bit+ designs where the noise floor matters.","metaTitle":"LM4040B10IDBZTG4 Shunt Voltage Reference, 10V ±0.2%","metaDescription":"Texas Instruments LM4040B10IDBZTG4 precision shunt reference, fixed 10V output, ±0.2% tolerance, 100ppm/°C drift, SOT-23-3 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Tolerance":"±0.2%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"15 mA","Current - Supply":"-","Current - Cathode":"125 µA","Base Product Number":"LM4040","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"180µVrms","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"100ppm/°C","Voltage - Output (Min/Fixed)":"10V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4040B10IDBZTG4/alternatives.json"},"ai":{"faq":[{"question":"Is LM4040B10IDBZTG4 obsolete or end-of-life?","answer":"No. There is no record of obsolescence or end-of-life notification from Texas Instruments."},{"question":"Can LM4040B10IDBZTG4 be used with a 5V supply?","answer":"No. This is a shunt reference with a fixed 10V output. A 5V supply is below the minimum operating voltage required to bias the reference into regulation. For a 5V rail, consider a lower-voltage variant in the LM4040 family (e.g., 2.5V or 4.096V outputs)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM4040B10IDBZTG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM4040B10IDBZTG4 when reusing this data.
