It operates as a two-terminal shunt device, drawing a cathode current of 88 µA typical while supplying up to 15 mA to the load. ## Tolerance and temperature drift — the so-what For a 12-bit ADC with a 4.096V reference, that drift contributes about 1 LSB of error over the full temperature span — acceptable for most industrial control loops but worth derating for a 16-bit converter.","metaTitle":"LM4040B41IDBZTG4 Shunt Reference, 4.096V ±0.2%, SOT-23-3","metaDescription":"TI LM4040B41IDBZTG4 precision shunt voltage reference, fixed 4.096V output, ±0.2% tolerance, 80 µVrms noise, 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":"88 µA","Base Product Number":"LM4040","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"80µVrms","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"100ppm/°C","Voltage - Output (Min/Fixed)":"4.096V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4040B41IDBZTG4/alternatives.json"},"ai":{"faq":[{"question":"Is LM4040B41IDBZTG4 RoHS compliant?","answer":"Yes, the part is RoHS compliant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM4040B41IDBZTG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM4040B41IDBZTG4 when reusing this data.
