For a BOM that already qualifies this reference, the supply channel is the standard distribution network, not surplus or broker inventory. The Automotive, AEC-Q100 series designation means the part has passed the full suite of automotive reliability stress tests: high-temperature operating life, temperature cycling, and ESD qualification to the AEC-Q100 Grade 1 temperature range of -40°C to 125°C ambient. ## Dual output voltages and the drift that matters This is a series voltage reference with two fixed output options selected at the factory: 2.048V or 4.096V. The 8ppm/°C temperature coefficient means the output voltage shifts less than 0.8 mV over the full -40°C to 125°C range at the 4.096V setting — relevant for an ADC reference that must hold accuracy across an engine bay's thermal cycle. The low-frequency noise spec of 12ppmp-p from 0.1 Hz to 10 Hz sets the noise floor for precision measurement chains. For a 16-bit ADC with a 4.096V reference, this noise contribution is roughly 50 µV peak-to-peak — below one LSB for most automotive sensor interfaces. Supply current is 460 µA typical, and the output can source up to 20 mA. The 20 mA capability means a single REF2041 can drive multiple ADC reference inputs or a small resistive load without an external buffer — the 460 µA quiescent draw is the penalty for keeping the reference powered in an always-on module. ## Package and supply rail constraints Housed in the SOT-23-5 Thin (TSOT-23-5) package, the footprint is 2.9 mm × 1.6 mm with a 0.95 mm pin pitch — the same land pattern as the standard SOT-23-5, so no special pad geometry is needed. The thin profile (1.0 mm max height) clears low-profile enclosures. Input voltage range is 4.116V to 5.5V. The lower bound of 4.116V is the minimum headroom above the 4.096V output — the reference needs at least 20 mV of dropout. On a nominal 5V rail, a 4.75V minimum supply still leaves 634 mV of margin; on a 3.3V rail the 2.048V output is the only viable option. Surface-mount assembly with the TSOT-23-5 package follows standard reflow profiles per JEDEC J-STD-020. The package is compatible with both Tape & Reel (TR) and Cut Tape (CT) delivery formats for prototyping or production volume.","metaTitle":"REF2041QDDCRQ1 Texas Instruments Voltage Reference","metaDescription":"Texas Instruments REF2041QDDCRQ1 automotive series voltage reference, dual fixed outputs 2.048V/4.096V, 8ppm/°C drift, TSOT-23-5.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Tolerance":"±0.05%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"SOT-23-5 Thin, TSOT-23-5","Reference Type":"Series","Voltage - Input":"4.116V ~ 5.5V","lifecycle_stage":"eol_hot","Current - Output":"20 mA","Current - Supply":"460µA","Noise - 0.1Hz to 10Hz":"12ppmp-p","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"SOT-23-THIN","Temperature Coefficient":"8ppm/°C","Voltage - Output (Min/Fixed)":"2.048V, 4.096V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.63","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.63000","currency":"USD"},{"qty":10,"price":"$5.05800","currency":"USD"},{"qty":25,"price":"$4.78120","currency":"USD"},{"qty":100,"price":"$4.14380","currency":"USD"},{"qty":250,"price":"$3.93132","currency":"USD"},{"qty":500,"price":"$3.52756","currency":"USD"},{"qty":1000,"price":"$2.97506","currency":"USD"},{"qty":3000,"price":"$1.76644","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4d6e6633c98033bfab27c36a48b0d909.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/REF2041QDDCRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/REF2041QDDCRQ1 when reusing this data.
