Its ±0.2% initial tolerance and 30ppm/°C temperature coefficient deliver the accuracy needed for ADC references, sensor excitation, and supply monitoring in engine-control units, body controllers, and infotainment modules. ## Low cathode current and output drive The 1 µA minimum cathode current lets this reference operate from a high-impedance bias resistor with minimal quiescent loss — useful in always-on automotive modules where every microamp counts. The 20 mA output current capability is generous for a shunt reference; it can drive multiple ADC inputs or a small resistive load while maintaining regulation. The shunt topology means the part sinks current from the supply through an external resistor; total current draw equals the load current plus the 1 µA minimum bias, so efficiency depends on the supply voltage and load conditions. ## Package and mounting The SOT-23-3 (TO-236-3 / SC-59 compatible) footprint is a standard three-pin surface-mount package. The shunt reference needs only one external resistor between the supply and the cathode pin. ## Lifecycle and sourcing reality It is a current-production part from Maxim Integrated (now part of Analog Devices), qualified under the Automotive AEC-Q100 series. The RoHS non-compliant marking means this variant uses lead-bearing terminations — verify your assembly house's exemption policy if you require full RoHS compliance.","metaTitle":"MAX6009AEUR-T Voltage Reference, 3V Fixed ±0.2% SOT-23-3","metaDescription":"Maxim MAX6009AEUR-T shunt voltage reference: 3V fixed output, ±0.2% tolerance, 30ppm/°C tempco, AEC-Q100 automotive qualified, SOT-23-3.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"Automotive, AEC-Q100","Package":"Bulk","Tolerance":"±0.2%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Reference Type":"Shunt","lifecycle_stage":"eol_hot","Current - Output":"20 mA","Current - Cathode":"1 µA","Noise - 0.1Hz to 10Hz":"75µVp-p","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"30ppm/°C","Voltage - Output (Min/Fixed)":"3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.66","stockQuantity":0,"priceTiers":[{"qty":181,"price":"$1.66000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d1fe3bb991b439e6c9dd6c44436108c9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the tolerance and temperature coefficient of MAX6009AEUR-T?","answer":"Initial tolerance is ±0.2%, and the temperature coefficient is 30ppm/°C over the -40°C to 85°C operating range."},{"question":"Is MAX6009AEUR-T automotive qualified?","answer":"Yes, the MAX6009AEUR-T is part of the Automotive, AEC-Q100 series, making it qualified for automotive applications including under-hood and cabin environments within its -40°C to 85°C temperature range."},{"question":"What is the difference between MAX6009 and MAX6008?","answer":"The MAX6009 provides a 3V fixed output, while the MAX6008 provides a different fixed voltage (typically 2.5V or other options depending on the suffix).
