Output noise is specified at 45 µVp-p over 0.1 Hz to 10 Hz and 128 µVrms over 10 Hz to 10 kHz. For a 12-bit ADC with a 4.096 V reference, the 45 µVp-p low-frequency noise corresponds to roughly 0.045 LSB — negligible for most acquisition chains. The 75 ppm/°C temperature coefficient means the output shifts about 0.3 mV over a 100°C swing, which a system calibration routine can absorb. ## SOT-23-3 package and temperature grade Housed in a 3-pin SOT-23-3 (TO-236-3 / SC-59 equivalent) surface-mount package, the REF3040AIDBZR fits tight PCB layouts.","metaTitle":"TI REF3040AIDBZR Voltage Reference, 4.096 V, ±0.2%","metaDescription":"Texas Instruments REF3040AIDBZR series voltage reference, fixed 4.096 V output, ±0.2% tolerance, SOT-23-3, -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":"4.146V ~ 5.5V","lifecycle_stage":"eol_hot","Current - Output":"25 mA","Current - Supply":"50µA","Base Product Number":"REF3040","Noise - 0.1Hz to 10Hz":"45µVp-p","Noise - 10Hz to 10kHz":"128µVrms","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"75ppm/°C","Voltage - Output (Min/Fixed)":"4.096V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1800","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/REF3040AIDBZR/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/REF3040AIDBZR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/REF3040AIDBZR when reusing this data.
