Accuracy versus Resolution

Tech Note

Accuracy is the measurement device’s degree of absolute correctness, whereas resolution is the smallest number that can be displayed or recorded by the measurement device.

The topic of resolution requires attention as it relates to overall accuracy. Many times distinguishing between accuracy and resolution is misinterpreted in determining system needs. Some examples and illustrations are presented in this Application Note in an attempt to show you that there is a significant difference between accuracy and resolution, even though they are related.
