The SC-70-5 package (also listed as 5-TSSOP / SOT-353) saves board area in space-constrained designs. ## 12 mA output and 80 µA cathode current The reference can source up to 12 mA of output current, which is enough to bias a single ADC reference input or a comparator threshold divider. ## Noise floor and temperature drift Wideband noise is specified at 20 µVrms over a 10 Hz to 10 kHz bandwidth — low enough for a 10-bit ADC reference but not for a 16-bit precision chain without averaging.","metaTitle":"LM4041D12IDCKR Shunt Voltage Reference, 1.225 V Fixed, ±1%","metaDescription":"Texas Instruments LM4041D12IDCKR shunt voltage reference, fixed 1.225 V output, ±1% tolerance, 150 ppm/°C drift, SC-70-5 package, -40°C to 85°C.","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); Cut Tape (CT)","Tolerance":"±1%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"5-TSSOP, SC-70-5, SOT-353","Product Status":"Active","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)","Supplier Device Package":"SC-70-5","Temperature Coefficient":"150ppm/°C","Voltage - Output (Min/Fixed)":"1.225V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/50fc5e198ec353cb298db1954beef248.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4041D12IDCKR/alternatives.json"},"ai":{"faq":[{"question":"What are equivalent or replacement parts for LM4041D12IDCKR?","answer":"Within the LM4041 family, the same SC-70-5 footprint is shared across tolerance grades (A/B/C/D).
