The ±0.5% initial tolerance places it in the mid-grade precision tier — adequate for 8- to 10-bit ADC references and general-purpose biasing where a 10V rail is needed. ## Noise and temperature drift Output noise is specified at 180 µVrms over the 10 Hz to 10 kHz band. For a 10V reference that is about 18 ppm of the output — acceptable for most industrial and instrumentation circuits, though a lower-noise reference would be preferred for 16-bit+ systems. The temperature coefficient is 100 ppm/°C, which translates to roughly 1 mV of drift over a 100°C span. Housed in a 5-lead SC-70-5 (also SOT-353) package, the LM4040C10IDCKR occupies minimal board area — about 2.0 mm × 2.1 mm.","metaTitle":"LM4040C10IDCKR 10V Shunt Voltage Reference, ±0.5%, SC-70-5","metaDescription":"Texas Instruments LM4040C10IDCKR precision 10V shunt reference, ±0.5% tolerance, 15 mA output, SC-70-5 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","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":"125 µA","Base Product Number":"LM4040","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"180µVrms","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SC-70-5","Temperature Coefficient":"100ppm/°C","Voltage - Output (Min/Fixed)":"10V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3990","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4040C10IDCKR/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum cathode current for LM4040C10IDCKR?","answer":"The maximum continuous cathode current is 15 mA.
