The ±1% initial tolerance provides adequate accuracy for many general-purpose designs without trimming. ## Noise and temperature drift Output noise is specified at 80µVrms over a 10Hz to 10kHz bandwidth, which is low enough for 12-bit ADC systems without additional filtering. ## Cathode current and output drive The shunt reference requires a minimum cathode current of 88 µA to maintain regulation, and can sink up to 15 mA of output current. This 15 mA ceiling limits how many loads the reference can drive — typically one ADC reference input or a few comparator thresholds. The bias resistor value must be calculated from the supply rail and the total load current to keep the cathode current within this range.","metaTitle":"TI LM4040D41IDCKR Shunt Voltage Reference, 4.096V ±1%","metaDescription":"Texas Instruments LM4040D41IDCKR precision shunt reference, fixed 4.096V output, ±1% tolerance, 80µVrms noise, SC-70-5 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); Cut Tape (CT)","Tolerance":"±1%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"5-TSSOP, SC-70-5, SOT-353","Product Status":"Active","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":"SC-70-5","Temperature Coefficient":"150ppm/°C","Voltage - Output (Min/Fixed)":"4.096V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8300","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4040D41IDCKR/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM4040D41IDCKR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM4040D41IDCKR when reusing this data.
