For an 18-bit ADC with a 2.048 V full-scale range, 1 LSB is roughly 7.8 µV — the reference noise alone consumes nearly a full code of the noise budget. In a 24-bit sigma-delta converter, that 6 µVp-p noise limits the effective resolution to about 18 noise-free bits unless the reference is averaged or filtered externally. ## 2.7 V to 18 V input — one rail, no regulator The input voltage range of 2.7 V to 18 V lets the REF5020MDREP run directly from a 3.3 V, 5 V, or 12 V supply bus without an intermediate LDO. The 1.25 mA quiescent supply current is the price of that flexibility — at 10 mA output current the dropout is just the headroom needed above 2.048 V, so the reference stays in regulation as long as the input stays above about 2.2 V.","metaTitle":"REF5020MDREP 2.048V Series Voltage Reference, ±0.05%","metaDescription":"Texas Instruments REF5020MDREP precision series voltage reference: 2.048V fixed output, ±0.05% tolerance, 5ppm/°C drift, 6µVp-p noise.","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-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","Reference Type":"Series","Voltage - Input":"2.7V ~ 18V","lifecycle_stage":"eol_hot","Current - Output":"10 mA","Current - Supply":"1.25mA","Base Product Number":"REF5020","Noise - 0.1Hz to 10Hz":"6µVp-p","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-55°C~125°C(TA)","Supplier Device Package":"8-SOIC","Temperature Coefficient":"5ppm/°C","Voltage - Output (Min/Fixed)":"2.048V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.2200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/db086d261922de7a70e7f7e2d7c7e788.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/REF5020MDREP/alternatives.json"},"ai":{"faq":[{"question":"Can REF5020MDREP replace REF5020ID?","answer":"Yes — both parts share the same 8-SOIC package, 2.048 V fixed output, ±0.05% tolerance, and 5 ppm/°C drift.
