That tolerance means the output sits between 2.046976V and 2.049024V at 25°C — tight enough to serve as the reference for a 12-bit SAR ADC without external trimming, and still within the error budget of many 16-bit delta-sigma converters when the system gain is calibrated once. ## 3ppm/°C drift and 3µVp-p noise — the stability story That works out to about 1.2 mV of total drift from cold to hot — a figure that keeps the reference error below one LSB in a 12-bit system at 2.048V full-scale. ## Input range and output drive — sizing the rail and the load Output current is rated at 10 mA — enough to drive the reference input of multiple ADCs or a small resistive divider network without an external buffer. Quiescent supply current is 1.2 mA, which keeps the self-heating low in a sealed enclosure. No official successor or second-source alternate is listed, so the BOM should be qualified with this exact part number.","metaTitle":"Texas Instruments REF5020ID Precision Voltage Reference","metaDescription":"Texas Instruments REF5020ID series voltage reference: 2.048V fixed output, ±0.05% tolerance, 3µVp-p noise, 3ppm/°C drift, -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":"Tube","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":"1.2mA","Base Product Number":"REF5020","Noise - 0.1Hz to 10Hz":"3µVp-p","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"8-SOIC","Temperature Coefficient":"3ppm/°C","Voltage - Output (Min/Fixed)":"2.048V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.8000","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/REF5020ID/alternatives.json"},"ai":{"faq":[{"question":"What is the typical noise performance of the REF5020ID?","answer":"The REF5020ID specifies 3 µVp-p noise over the 0.1 Hz to 10 Hz band.
