The output is adjustable via an external resistor divider from a minimum of 1.233 V up to 10 V. For a 1.233 V output, that drift works out to roughly 12.3 mV worst-case across the full span — enough to matter in a 12-bit ADC reference path but acceptable for general-purpose comparator thresholds and bias supplies. ## Biasing and load limits The external series resistor must be sized to deliver between those limits across the full input voltage range and load variation. A 1 kΩ resistor from a 5 V rail, for example, biases the reference at roughly 3.8 mA — well within the operating window and leaving headroom for transient loads. Wideband noise is specified at 20 µVrms over the 10 Hz to 10 kHz band — a clean enough floor for most 10- to 12-bit ADC references, though a lower-noise series reference would be preferred for 16-bit or higher-resolution signal chains.","metaTitle":"TI LM4041CIDBZTG4 Shunt Voltage Reference, ±0.5%, SOT-23-3","metaDescription":"Texas Instruments LM4041CIDBZTG4 precision shunt reference, adjustable output to 10 V, ±0.5% tolerance, 100 ppm/°C drift, 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":"-","Package":"Tape & Reel (TR)","Tolerance":"±0.5%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"12 mA","Current - Supply":"-","Current - Cathode":"80 µA","Base Product Number":"LM4041","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"20µVrms","Operating Temperature":"-40°C~85°C(TA)","Voltage - Output (Max)":"10 V","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"100ppm/°C","Voltage - Output (Min/Fixed)":"1.233V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/97120b7526b8b1f1915487ff781cf597.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4041CIDBZTG4/alternatives.json"},"ai":{"faq":[{"question":"Is LM4041CIDBZTG4 equivalent to LM4041A?","answer":"Both are part of the same LM4041 shunt reference family and share the same SOT-23-3 footprint and pinout.
