The 0.1 Hz to 10 Hz noise is 36 µVp-p, and the 10 Hz to 10 kHz noise is 105 µVrms — figures that place it in the mid-tier precision band, adequate for 12-bit to 14-bit signal chains where the reference noise contribution stays below 1 LSB. ## 50 µA quiescent — sized for always-on and battery rails The supply current is 50 µA typical. The input voltage range is 3.35 V to 5.5 V. Output current is rated at 25 mA, enough to bias a handful of ADC reference inputs or an op-amp front end without an external buffer.","metaTitle":"Texas Instruments REF3033AIDBZRG4 Voltage Reference","metaDescription":"Texas Instruments REF3033AIDBZRG4 series voltage reference, fixed 3.3V output, ±0.2% tolerance, 36µVp-p noise (0.1-10Hz), 50µA supply, -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":"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":"3.35V ~ 5.5V","lifecycle_stage":"eol_hot","Current - Output":"25 mA","Current - Supply":"50µA","Base Product Number":"REF3033","Noise - 0.1Hz to 10Hz":"36µVp-p","Noise - 10Hz to 10kHz":"105µVrms","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"75ppm/°C","Voltage - Output (Min/Fixed)":"3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4200","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/REF3033AIDBZRG4/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/REF3033AIDBZRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/REF3033AIDBZRG4 when reusing this data.
