Datasheet - Application Information
8.4 Accuracy of the Encoder System
This section enlightens on the individual factors that influence the accuracy of the encoder system, and provides techniques to improve them.
Accuracy is defined as the difference between measured angle and actual angle. This is not to be confused with resolution, which is the smallest
step that the system can resolve. The two parameters are not necessarily linked together. A high resolution encoder may not necessarily be
highly accurate as well.
8.4.1   Quantization Error
There is however a direct link between resolution and accuracy, which is the quantization error:
Figure 25. Quantization Error of a Low Resolution and a High Resolution System
The resolution of the encoder determines the smallest step size. The angle error caused by quantization cannot get better than ??LSB. As
shown in Figure 25, a higher resolution system (right picture) has a smaller quantization error, as the step size is smaller. For the AS5130, the
quantization error is ??LSB = ?0.7?/DIV>
