It's a common choice for portable instrumentation, data-acquisition front-ends, and battery-powered gear where a stable voltage reference is needed without a separate supply rail. The SOT-23-3 package is small enough for tight layouts but still easy to hand-solder with a fine tip iron — no hot-air rework station required. With 35µVrms noise over a 10Hz to 10kHz bandwidth and a temperature coefficient of 150ppm/°C, this reference keeps the voltage stable enough for a 12-bit ADC without additional filtering. The 70 µA minimum cathode current means it can run from a simple resistor divider off a higher rail, which simplifies the power budget.","metaTitle":"LM4040EIM3X-2.0/NOPB Shunt Voltage Reference, 2.048V, ±2%","metaDescription":"Texas Instruments LM4040EIM3X-2.0/NOPB precision shunt reference, fixed 2.048V output, ±2% tolerance, 35µVrms noise, 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":"±2%","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":"70 µA","Base Product Number":"LM4040","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"35µVrms","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"150ppm/°C","Voltage - Output (Min/Fixed)":"2.048V"}},"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/LM4040EIM3X-2.0%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy LM4040EIM3X-2.0/NOPB available via RFQ confirmation?","answer":"This part is obsolete but available through our independent sourcing channel.
