The minimum cathode current is 65 µA — below this the reference may drop out of regulation, so the series resistor must be sized to keep at least 65 µA flowing into the cathode at all load conditions. The temperature coefficient is 150 ppm/°C, and wideband noise from 10 Hz to 10 kHz is specified at 20 µVrms. For a 1.225 V reference, this noise floor is low enough for 12-bit ADC applications without additional filtering. The LM4041EIM7-1.2 is listed as Obsolete. Texas Instruments has discontinued this specific grade/package variant.","metaTitle":"LM4041EIM7-1.2 Shunt Reference, 1.225V Fixed, ±2%, SC-70-5","metaDescription":"Texas Instruments LM4041EIM7-1.2 precision shunt voltage reference, 1.225V fixed output, ±2% tolerance, 12 mA output, SC-70-5.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Tolerance":"±2%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"5-TSSOP, SC-70-5, SOT-353","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":"SC-70-5","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/d2855eaed3a119e1ade8ae46dfbd1dff.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4041EIM7-1.2/alternatives.json"},"ai":{"faq":[{"question":"Is the LM4041EIM7-1.2 obsolete?","answer":"Yes, the LM4041EIM7-1.2 is listed as Obsolete.

It typically offers tighter tolerance (±0.1% or ±0.5%) and a wider temperature range, making it a pin-compatible, performance-superior drop-in replacement.
