Fixed 4.096 V reference in a SOT-23-3
The Texas Instruments REF2940AIDBZT is a series voltage reference that outputs a fixed 4.096 V with ±2% initial tolerance. It draws 59 µA quiescent supply current and operates over -40°C to 125°C, making it a fit for industrial sensor interfaces, data-acquisition front-ends, and automotive modules where a stable 4.096 V rail is needed for an ADC or DAC reference. The SOT-23-3 package (SC-59, TO-236-3 compatible) keeps board area small and suits reflow assembly.
