The 10 mA output current can sink or source enough to bias multiple op-amps or a small ADC reference input without a buffer.","metaTitle":"Texas Instruments REF5020IDRG4 Voltage Reference, 2.048V","metaDescription":"TI REF5020IDRG4 series voltage reference, fixed 2.048V output, ±0.05% tolerance, 3µVp-p noise, 3ppm/°C drift, -40°C to 125°C, SOIC-8.","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)","Tolerance":"±0.05%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","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":"$3.3700","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/REF5020IDRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the noise specification for the REF5020IDRG4?","answer":"The noise from 0.1 Hz to 10 Hz is 3 µVp-p. This low noise floor makes it suitable for driving the reference input of a 16-bit SAR ADC without additional filtering."},{"question":"Can the REF5020IDRG4 replace the REF5020IDR?","answer":"The REF5020IDRG4 and REF5020IDR share the same die and electrical specifications. The only difference is the packaging format: the RG4 suffix denotes Tape & Reel, while the IDR suffix is typically Tube. The pinout and footprint are identical, so a direct replacement is possible if the reel format fits the production line."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/REF5020IDRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/REF5020IDRG4 when reusing this data.
