- Microcontroller analog-to-digital converter (ADC) references
Procurement Notes
Verify the specific suffix configuration against official datasheets to ensure compatibility with required accuracy grades and package types. Confirm RoHS compliance status and lead times through authorized distribution channels prior to procurement planning.
Selection Notes
Select this component when a stable 2.048 V reference is needed with moderate precision requirements. Consider the 150 ppm/°C temperature coefficient and 0.5% initial accuracy limits against system specifications. Ensure the operating environment remains within the specified -40°C to +85°C range for optimal performance.
Part Context
This part belongs to the LM4040-N family of micropower shunt voltage references from Texas Instruments. The series offers various fixed output voltages and accuracy grades in small packages, serving as a standard solution for reference needs in general-purpose electronic equipment and industrial control applications.
Replacement Considerations
Check for direct equivalents such as LM4040AIM3X-2.0 or LM4040DIM3X-2.0/NOPB based on required accuracy and temperature coefficient specifications. Verify pinout compatibility and thermal characteristics before substituting.
