The shunt architecture means it operates like a two-terminal Zener — the load and the bias resistor share the same current path, so the 15 mA maximum output current and the 95 µA minimum cathode current together define the resistor value and the power budget. ## Obsolete — no official successor on record ## SOT-23-3 package — footprint and rework note","metaTitle":"LM4040CIM3X-8.2/NOPB Shunt Reference, 8.192 V, ±0.5%","metaDescription":"Texas Instruments LM4040CIM3X-8.2/NOPB precision shunt voltage reference, fixed 8.192 V output, ±0.5% tolerance, SOT-23-3 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Tolerance":"±0.5%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Obsolete","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"15 mA","Current - Supply":"-","Current - Cathode":"95 µA","Base Product Number":"LM4040","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"130µVrms","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"100ppm/°C","Voltage - Output (Min/Fixed)":"8.192V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8c40cf163b5cda64fd88ad5c9f25fe6d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4040CIM3X-8.2%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Is LM4040CIM3X-8.2/NOPB obsolete?","answer":"Yes, the LM4040CIM3X-8.2/NOPB is officially Obsolete.
