The minimum cathode current is 125 µA, and the maximum continuous output current is 15 mA.","metaTitle":"LM4040A10IDBZRG4 10V Shunt Reference, ±0.1%, SOT-23-3","metaDescription":"Texas Instruments LM4040A10IDBZRG4 precision 10V shunt voltage reference. ±0.1% tolerance, 100 ppm/°C drift, SOT-23-3.","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":"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/LM4040A10IDBZRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the temperature coefficient of LM4040A10IDBZRG4?","answer":"The temperature coefficient is 100 ppm/°C."},{"question":"Is LM4040A10IDBZRG4 a good choice for a 10V reference?","answer":"Yes, for applications requiring a fixed 10V reference with ±0.1% accuracy and low drift in a small SOT-23-3 package.
