AS5030 8-bit Programmable Magnetic Rotary Encoder
4~400ms. At sampling intervals >400ms, the power cycling mode is the best method to minimize the average current
consumption.
The curves are based on the figures given in 8.1.

This chapter describes which individual factors influence the accuracy of the encoder system and how 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.
9.1
There is however a direct link between resolution and accuracy, which is the quantization error:
