The 80 µVrms noise spec (10 Hz to 10 kHz) is clean enough for a 12-bit ADC reference without additional filtering in most layouts. The SOT-23-3 footprint is shared across the LM4040 family, so a pin-compatible alternate within the same series is straightforward if a different voltage or tolerance tier is needed.","metaTitle":"LM4040A41IDBZRG4 Shunt Voltage Reference, 4.096 V ±0.1%","metaDescription":"Texas Instruments LM4040A41IDBZRG4 precision shunt voltage reference, fixed 4.096 V output, ±0.1% tolerance, 100 ppm/°C drift, SOT-23-3, active production.","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":"±0.1%","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/LM4040A41IDBZRG4/alternatives.json"},"ai":{"faq":[{"question":"What package does the LM4040A41IDBZRG4 come in?","answer":"It is supplied in a SOT-23-3 surface-mount package (also listed as TO-236-3 / SC-59).
