The maximum output current is 12 mA, so the series resistor from the supply rail must be sized to deliver at least 80 µA to the cathode while keeping the total load plus reference current under 12 mA. ## Temperature drift and noise floor The temperature coefficient is 100 ppm/°C, which means a 50°C swing shifts the output by about 0.5% — fine for a 10-bit ADC, marginal for a 12-bit without calibration. Noise from 10 Hz to 10 kHz is 20 µVrms, low enough that it won't dominate the LSB of a 12-bit converter at a 2.5 V reference.","metaTitle":"TI LM4041BIDBZTG4 Shunt Voltage Reference, ±0.2% Tolerance","metaDescription":"Texas Instruments LM4041BIDBZTG4 adjustable shunt reference, ±0.2% tolerance, 1.233 V to 10 V output, 80 µA cathode current, 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":"±0.2%","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/LM4041BIDBZTG4/alternatives.json"},"ai":{"faq":[{"question":"Is LM4041BIDBZTG4 equivalent to LM4041BIDBZT?","answer":"The LM4041BIDBZT is the same die in a different reel/tube packaging variant.
