It operates as a two-terminal shunt device, requiring only a series resistor from the supply to set the bias current — the cathode current floor is 95 µA, and it can sink up to 15 mA of output current. The SOT-23-3 package (also known as TO-236-3 or SC-59) is a standard surface-mount footprint that mates with common PCB land patterns.","metaTitle":"LM4040AIM3X-8.2/NOPB Shunt Reference, 8.192V ±0.1%, SOT-23-3","metaDescription":"Texas Instruments LM4040AIM3X-8.2/NOPB precision shunt voltage reference, fixed 8.192V output, ±0.1% tolerance, 100ppm/°C drift, SOT-23-3.","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":"±0.1%","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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8c40cf163b5cda64fd88ad5c9f25fe6d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4040AIM3X-8.2%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Is LM4040AIM3X-8.2/NOPB obsolete?","answer":"Yes, the LM4040AIM3X-8.2/NOPB is listed as Obsolete.
