As a shunt reference, it behaves like a precision Zener diode — it requires a bias resistor from the supply to set the operating current, and the load draws current from the same node. The minimum cathode current is 88 µA, and the device can source up to 15 mA to the load while maintaining regulation. ## Temperature drift and noise floor for industrial signal chains This low-noise characteristic makes the part suitable for precision measurement chains where the reference noise must not dominate the ADC's quantization noise floor. ## Active lifecycle and SC-70-5 footprint planning The device is offered in a 5-pin SC-70-5 package (also known as SOT-353).","metaTitle":"LM4040B41IDCKR Shunt Voltage Reference, 4.096 V ±0.2%","metaDescription":"Texas Instruments LM4040B41IDCKR precision shunt reference: 4.096 V fixed output, ±0.2% tolerance, 100 ppm/°C drift, 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":"±0.2%","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":"100ppm/°C","Voltage - Output (Min/Fixed)":"4.096V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1445","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4040B41IDCKR/alternatives.json"},"ai":{"faq":[{"question":"What is the tolerance of the LM4040B41IDCKR?","answer":"Initial tolerance is ±0.2%, placing it in the precision tier suitable for 12-bit systems without trimming."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM4040B41IDCKR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM4040B41IDCKR when reusing this data.
