It delivers a fixed 4.096 V output with ±1% initial tolerance — a common bias voltage for 12-bit and 16-bit ADC reference inputs in engine-control and battery-management modules. Output current is rated 20 mA, enough to drive the reference input of multiple converters or a small sensor bridge. ## Noise, drift, and thermal range For a 4.096 V reference, that drift adds up to about 0.41 mV over a 100 °C swing — well within the ±1% tolerance budget for most automotive sensor chains. Operating temperature covers -40°C to 125°C (junction), which matches the AEC-Q100 Grade 1 band. That means it is qualified for under-hood or cabin-ambient environments where the PCB sees sustained 105°C. Housed in an SC-74A / SOT-753 package (also called SOT-23-5), the part is a 5-pin surface-mount device with 0.95 mm pitch. The small footprint fits tight automotive ECU layouts, and the 100 µA quiescent supply current keeps the thermal budget low even in dense boards.","metaTitle":"LM4128DQ1MF4.1/NOPB 4.096V Series Voltage Reference","metaDescription":"Texas Instruments LM4128DQ1MF4.1/NOPB series voltage reference, 4.096V fixed output, ±1% tolerance, AEC-Q100 qualified, SOT-23-5.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Tolerance":"±1%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","Reference Type":"Series","Voltage - Input":"4.496V ~ 5.5V","lifecycle_stage":"eol_hot","Current - Output":"20 mA","Current - Supply":"100µA","Noise - 0.1Hz to 10Hz":"350µVp-p","Operating Temperature":"-40°C ~ 125°C (TJ)","Supplier Device Package":"SOT-23-5","Temperature Coefficient":"100ppm/°C","Voltage - Output (Min/Fixed)":"4.096V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.12","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.12000","currency":"USD"},{"qty":10,"price":"$2.80600","currency":"USD"},{"qty":25,"price":"$2.64720","currency":"USD"},{"qty":100,"price":"$2.25550","currency":"USD"},{"qty":250,"price":"$2.11788","currency":"USD"},{"qty":500,"price":"$1.85314","currency":"USD"},{"qty":1000,"price":"$1.53546","currency":"USD"},{"qty":2000,"price":"$1.49850","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d0a8321878fcc5289c7be83212ba7ad8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LM4128DQ1MF4.1/NOPB AEC-Q100 qualified?","answer":"Yes, it is part of the Automotive, AEC-Q100 series, meaning it meets automotive IC qualification requirements including temperature grade and reliability stress."},{"question":"How does LM4128DQ1MF4.1/NOPB compare to the LM4132AMF-4.1/NOPB?","answer":"The LM4132AMF-4.1/NOPB offers a tighter ±0.05% tolerance and a lower 20 ppm/°C temperature coefficient, but shares the same 4.096 V output, 20 mA output current, and 100 µA supply current.
