The 35µVrms noise over 10Hz to 10kHz and 100ppm/°C temperature coefficient make it suitable for precision analog chains in industrial control and instrumentation where a stable reference voltage is needed. No official successor or last-time-buy window is recorded. ## Parametric profile for BOM fit As a shunt reference, the LM4040CIM7-2.5/NOPB requires a cathode resistor to set the bias current; the minimum cathode current is 65 µA and the output can sink up to 15 mA. The SC-70-5 (SOT-353) package occupies minimal board area, but the small footprint makes manual rework or hot-air removal more delicate than a larger SOT-23.","metaTitle":"LM4040CIM7-2.5/NOPB Shunt Voltage Reference, 2.5V ±0.5%","metaDescription":"Texas Instruments LM4040CIM7-2.5/NOPB precision shunt reference, fixed 2.5V output, ±0.5% tolerance, 35µVrms noise.","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); Cut Tape (CT)","Tolerance":"±0.5%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"5-TSSOP, SC-70-5, SOT-353","Product Status":"Active","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"15 mA","Current - Supply":"-","Current - Cathode":"65 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":"SC-70-5","Temperature Coefficient":"100ppm/°C","Voltage - Output (Min/Fixed)":"2.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3627","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/db47fc1a31c797b619d88478be755429.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4040CIM7-2.5%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What is the tolerance of LM4040CIM7-2.5/NOPB?","answer":"The initial tolerance is ±0.5%, which is a C-grade device in the LM4040 family.
