Output noise is specified at 14µVp-p over 0.1Hz to 10Hz and 42µVrms over 10Hz to 10kHz — low enough to not limit a 12-bit ADC at 1.25V full scale, but worth checking if you're pushing 16-bit resolution. ## SOT-23-3 package — board layout notes Housed in a standard SOT-23-3 (TO-236-3 / SC-59) surface-mount package, the REF3012AIDBZR fits easily into compact mixed-signal layouts with a 0.95mm pin pitch.","metaTitle":"REF3012AIDBZR 1.25V voltage reference, ±0.2%, 75ppm/°C","metaDescription":"Texas Instruments REF3012AIDBZR series voltage reference, fixed 1.25V output, ±0.2% tolerance, 75ppm/°C drift, 50µA supply, 25mA output, SOT-23-3, -40°C to","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":"±0.2%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Active","Reference Type":"Series","Voltage - Input":"1.8V ~ 5.5V","lifecycle_stage":"eol_hot","Current - Output":"25 mA","Current - Supply":"50µA","Base Product Number":"REF3012","Noise - 0.1Hz to 10Hz":"14µVp-p","Noise - 10Hz to 10kHz":"42µVrms","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"75ppm/°C","Voltage - Output (Min/Fixed)":"1.25V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1800","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/REF3012AIDBZR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between REF3012AIDBZR and REF3012AIDBZT?","answer":"Electrically they are identical."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/REF3012AIDBZR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/REF3012AIDBZR when reusing this data.
