Its 10 mA output current can bias multiple ADC reference inputs or a DAC reference buffer without an external follower. Low-frequency noise is specified at 17 µVp-p from 0.1 Hz to 10 Hz, critical for precision measurement chains where 1/f noise limits effective resolution. ## Supply headroom and quiescent current Quiescent supply current is 135 µA typical, making it viable for battery-powered instrumentation where every microamp counts. Housed in a 3-pin SOT-23-3 (TO-236-3, SC-59) surface-mount package, it fits tight PCB layouts.","metaTitle":"REF3112AIDBZT Voltage Reference, 1.25 V Fixed, ±0.2%","metaDescription":"Texas Instruments REF3112AIDBZT series voltage reference, fixed 1.25 V output, ±0.2% tolerance, 20 ppm/°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":"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","Product Status":"Active","Reference Type":"Series","Voltage - Input":"1.8V ~ 5.5V","lifecycle_stage":"eol_hot","Current - Output":"10 mA","Current - Supply":"135µA","Base Product Number":"REF3112","Noise - 0.1Hz to 10Hz":"17µVp-p","Noise - 10Hz to 10kHz":"24µVrms","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"20ppm/°C","Voltage - Output (Min/Fixed)":"1.25V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.2000","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/REF3112AIDBZT/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/REF3112AIDBZT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/REF3112AIDBZT when reusing this data.
