The ±0.5% tolerance keeps the total error budget under 1% when combined with the ADC's own INL, avoiding the need for a trim pot in production. Output current is rated 12 mA, with a cathode current of 65 µA. The low cathode current means the reference draws minimal bias from the supply rail, which matters in battery-backed or always-on automotive modules where every microamp counts. Noise is specified at 20 µVrms over 10 Hz to 10 kHz. For a 12-bit ADC with a 3.3 V reference, this noise contribution is below 0.1 LSB, so it does not degrade the converter's effective resolution in most automotive sensor interfaces. ## SOT-23-3 package and temperature range The SOT-23-3 footprint is a common industry standard, so board layout reuse across reference designs is straightforward.","metaTitle":"LM4041QCIM3-1.2/NO Shunt Voltage Reference, AEC-Q100","metaDescription":"Texas Instruments LM4041QCIM3-1.2/NO automotive AEC-Q100 shunt reference, fixed 1.225 V output, ±0.5% tolerance, SOT-23-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Tolerance":"±0.5%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Active","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"12 mA","Current - Supply":"-","Current - Cathode":"65 µA","Base Product Number":"LM4041","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"20µVrms","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"100ppm/°C","Voltage - Output (Min/Fixed)":"1.225V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5501","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4041QCIM3-1.2%2FNO/alternatives.json"},"ai":{"faq":[{"question":"How does LM4041QCIM3-1.2/NO compare to the standard LM4041DIM3-1.2?","answer":"The key difference is the AEC-Q100 automotive qualification on the QCIM3 variant versus the standard commercial/industrial grade on the DIM3.
