The low quiescent draw suits battery-powered instrumentation where every microamp counts; the 12 mA ceiling handles most precision reference loads including multiple op-amp bias networks. ## 20 µVrms noise — clean enough for 12-bit, marginal for 16-bit Output noise is specified at 20 µVrms over 10 Hz to 10 kHz. That places the reference comfortably inside the noise budget for a 12-bit ADC with a 2.5 V full-scale; for 16-bit designs you will want to add a post-filter or step up to a lower-noise series reference. ## SOT-23-3 — footprint matches industry-standard shunt references The pinout is shared by many adjustable shunt references from multiple vendors, simplifying board-level replacement if an alternate source is qualified.","metaTitle":"LM4051AIM3X-ADJ Shunt Voltage Reference, ±0.1%, Adjustable","metaDescription":"LM4051AIM3X-ADJ precision shunt reference, ±0.1% tolerance, adjustable 1.212V to 10V, 50ppm/°C, SOT-23-3.","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":"±0.1%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","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":"LM4051","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":"50ppm/°C","Voltage - Output (Min/Fixed)":"1.212V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.1300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e499b7cd54f3272232db27a8df268948.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4051AIM3X-ADJ/alternatives.json"},"ai":{"faq":[{"question":"Is LM4051AIM3X-ADJ obsolete?","answer":"Yes, Texas Instruments lists LM4051AIM3X-ADJ as obsolete.
