It is designed for low-cost, space-constrained bias and reference circuits where a through-hole package simplifies prototyping and rework. ## Noise, drift, and cathode current — what matters for a reference Output noise is specified at 20µVrms over a 10 Hz to 10 kHz bandwidth, which is low enough for 8- to 10-bit ADC references in moderate-speed data acquisition or comparator threshold setting. The temperature coefficient is 150ppm/°C, a typical value for the E-grade LM4041 family. Minimum cathode current is 65 µA, and the shunt can sink up to 12 mA of output current. The wide operating range lets the same reference serve both low-power battery circuits and higher-current loads like LED drivers or sensor bridges. The part is no longer manufactured and is not available through the factory channel.","metaTitle":"LM4041EIZ-1.2/NOPB Shunt Reference, 1.225V Fixed, ±2%","metaDescription":"Texas Instruments LM4041EIZ-1.2/NOPB precision shunt reference, 1.225V fixed output, ±2% tolerance, 150ppm/°C drift, TO-92-3 through-hole.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Bulk","Tolerance":"±2%","Output Type":"Fixed","Mounting Type":"Through Hole","Package / Case":"TO-226-3, TO-92-3 (TO-226AA)","Product Status":"Obsolete","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~85°C(TA)","Supplier Device Package":"TO-92-3","Temperature Coefficient":"150ppm/°C","Voltage - Output (Min/Fixed)":"1.225V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/26af4fd2ab0c421228a4f1c33eae6ec2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4041EIZ-1.2%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Is LM4041EIZ-1.2/NOPB obsolete?","answer":"Yes, Texas Instruments lists the LM4041EIZ-1.2/NOPB as Obsolete.
