That 2.048 V is a natural span for 12-bit ADCs with a 0–2.048 V input range — every LSB lands at exactly 500 µV, making the math clean and the system error budget predictable. The series topology means the load current comes from the input supply, not the reference output, so the output stays stable even when the load varies. ## 25 mA output, 50 µA supply — driving the ADC reference input Rated for 25 mA continuous output current, this reference can drive the reference input of several successive-approximation ADCs simultaneously without an external buffer. The 50 µA quiescent supply current keeps the power budget tight in battery-powered or loop-powered designs — the reference itself draws less than the ADC's reference input current during conversion. ## SOT-23-3 package — footprint and storage Housed in a SOT-23-3 (TO-236-3, SC-59) surface-mount package, the REF3020AIDBZRG4 shares the same three-pin footprint as the rest of the REF3020 family. Store the reels in a dry cabinet — the SOT-23-3 body is not moisture-sensitive per JEDEC Level 1, but the tape and reel absorb humidity over long storage.","metaTitle":"REF3020AIDBZRG4 Voltage Reference, 2.048 V, ±0.2%, SOT-23-3","metaDescription":"Texas Instruments REF3020AIDBZRG4 series voltage reference, fixed 2.048 V output, ±0.2% tolerance, 75 ppm/°C drift, -40°C to 125°C, SOT-23-3.","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","Reference Type":"Series","Voltage - Input":"2.098V ~ 5.5V","lifecycle_stage":"eol_hot","Current - Output":"25 mA","Current - Supply":"50µA","Base Product Number":"REF3020","Noise - 0.1Hz to 10Hz":"23µVp-p","Noise - 10Hz to 10kHz":"65µVrms","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"75ppm/°C","Voltage - Output (Min/Fixed)":"2.048V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4200","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/REF3020AIDBZRG4/alternatives.json"},"ai":{"faq":[{"question":"Is REF3020AIDBZRG4 an exact equivalent for REF3020AIDBZT?","answer":"The REF3020AIDBZRG4 and REF3020AIDBZT share the same base product number (REF3020) and the same electrical specifications — 2.048 V output, ±0.2% tolerance, 75 ppm/°C drift, SOT-23-3 package.
