Low-frequency noise is specified at 27 µVp-p over 0.1 Hz to 10 Hz and 39 µVrms over 10 Hz to 10 kHz. For a 12-bit ADC with a 2.048 V reference, that noise contributes less than 0.5 LSB — it does not limit the converter's effective resolution. Supply current is 135 µA typical, which matters for always-on modules or battery-backed reference rails where every microamp counts. ## SOT-23-3 package and automotive qualification It is rated for production use in automotive modules, not just prototype evaluation.","metaTitle":"REF3120AQDBZRQ1 Voltage Reference, 2.048 V, ±0.2%, AEC-Q100","metaDescription":"Texas Instruments REF3120AQDBZRQ1 series voltage reference, 2.048 V fixed output, ±0.2% tolerance, 20 ppm/°C drift, AEC-Q100 qualified, -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":"Automotive, AEC-Q100","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":"2.098V ~ 5.5V","lifecycle_stage":"eol_hot","Current - Output":"10 mA","Current - Supply":"135µA","Base Product Number":"REF3120","Noise - 0.1Hz to 10Hz":"27µVp-p","Noise - 10Hz to 10kHz":"39µVrms","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"20ppm/°C","Voltage - Output (Min/Fixed)":"2.048V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a363e895f8ce8fed78119554515912e4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/REF3120AQDBZRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is REF3120AQDBZRQ1 pin-compatible with REF3120AIDBZR?","answer":"Both parts share the same base product number (REF3120) and the same SOT-23-3 package.
