The 3µVp-p noise from 0.1 Hz to 10 Hz is low enough that the reference itself is not the dominant noise source in a 16-bit SAR ADC chain — the ADC's own noise floor or the input driver will likely set the system limit. The 10 mA output current can drive the reference input of multiple ADCs or DACs simultaneously, so you can share one reference across several converters without adding a buffer. The input voltage range of 3.2V to 18V means it works from a 5V rail or a 12V unregulated supply — no separate pre-regulator needed. The 1.2mA quiescent supply current is low enough that the reference does not dominate the power budget in a battery-powered system. The small footprint fits tight analog front-end layouts. The supplier device package is 8-VSSOP — the same mechanical outline as the MSOP-8, so the PCB footprint is standard across the REF50xx family.","metaTitle":"REF5030IDGKR 3V Precision Voltage Reference, ±0.05%, 3ppm/°C","metaDescription":"Texas Instruments REF5030IDGKR series voltage reference: 3V fixed output, ±0.05% tolerance, 3ppm/°C drift, 3µVp-p noise, -40°C to 125°C.","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":"±0.05%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","Product Status":"Active","Reference Type":"Series","Voltage - Input":"3.2V ~ 18V","lifecycle_stage":"eol_hot","Current - Output":"10 mA","Current - Supply":"1.2mA","Base Product Number":"REF5030","Noise - 0.1Hz to 10Hz":"3µVp-p","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"8-VSSOP","Temperature Coefficient":"3ppm/°C","Voltage - Output (Min/Fixed)":"3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.1900","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/REF5030IDGKR/alternatives.json"},"ai":{"faq":[{"question":"What is the tolerance of REF5030IDGKR?","answer":"The initial tolerance is ±0.05%. That means a 3V output will be between 2.9985V and 3.0015V at 25°C without any external trimming."},{"question":"Can REF5030IDGKR work with a 3.3V input?","answer":"Yes. The input voltage range is 3.2V to 18V, so a 3.3V rail is within spec. The 3V output will regulate correctly as long as the input stays above 3.2V."},{"question":"Is REF5030IDGKR equivalent to REF5030IDGKT?","answer":"Electrically they are identical — same output voltage, tolerance, temperature coefficient, and noise. IDGKT is typically a different reel quantity or tube. For a BOM line, either works if the reel size matches your pick-and-place setup."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/REF5030IDGKR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/REF5030IDGKR when reusing this data.
