The shunt architecture means it operates like a two-terminal Zener: it draws the current set by the series resistor from cathode to ground. The minimum cathode current is 100 µA, and the maximum continuous output current is 15 mA. The design must ensure the cathode current stays within that window across the full input voltage and load range. For a 12-bit system with an 8.192 V reference, the LSB is 2 mV — the noise is roughly 6.5% of one LSB, which is acceptable for most industrial control and instrumentation applications without additional filtering. ## Temperature range and package — board-fit considerations The SOT-23-3 package (TO-236-3 / SC-59) is a three-lead surface-mount footprint with 0.95 mm pitch. It is pin-compatible with other SOT-23 shunt references in the LM4040 family, which matters when qualifying a replacement from surplus stock.","metaTitle":"LM4040DIM3X-8.2/NOPB Shunt Voltage Reference, 8.192V ±1%","metaDescription":"Texas Instruments LM4040DIM3X-8.2/NOPB precision shunt reference, 8.192V fixed output, ±1% tolerance, 130µVrms noise, -40°C to 85°C.","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":"±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":"100 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":"150ppm/°C","Voltage - Output (Min/Fixed)":"8.192V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2382","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8c40cf163b5cda64fd88ad5c9f25fe6d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4040DIM3X-8.2%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What is a suitable replacement for LM4040DIM3X-8.2/NOPB?","answer":"No official replacement is listed by Texas Instruments.
