Texas Instruments has ended production; no last-time-buy window remains open. New designs should not target this order code. No official successor is listed on the manufacturer's record. ## Shunt architecture and output current limits As a shunt reference, the LM4040CIZ-8.2/NOPB sinks current through the cathode to regulate the output voltage. ## Through-hole TO-92-3 — board-fit considerations The three leads are typically cathode, anode, and no-connect (NC) — the pinout is standard for this family but should be verified against the datasheet for the specific orientation. For high-volume through-hole assembly, plan for tube-fed or vibratory-bowl feeding.","metaTitle":"LM4040CIZ-8.2/NOPB Shunt Voltage Reference, 8.192 V, ±0.5%","metaDescription":"Texas Instruments LM4040CIZ-8.2/NOPB precision shunt reference, 8.192 V fixed output, ±0.5% tolerance, 100 ppm/°C drift, TO-92-3, obsolete.","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":"±0.5%","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":"15 mA","Current - Supply":"-","Current - Cathode":"95 µA","Base Product Number":"LM4040","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"130µVrms","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"TO-92-3","Temperature Coefficient":"100ppm/°C","Voltage - Output (Min/Fixed)":"8.192V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8c40cf163b5cda64fd88ad5c9f25fe6d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4040CIZ-8.2%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Is LM4040CIZ-8.2/NOPB obsolete?","answer":"Yes, the manufacturer has marked this part as Obsolete.
