TMAG5170-Q1: Testing method to verify the accuracy

Hello Jun,

Thanks for posting on the PS forum. Not sure if I understood the question correctly, but if  you are looking for a way to verify TMAG5170's accuracy in a system  we do have a reference design TIDA-060040. In the design guidelines document we go over some of the testing method that was done for this reference design. It also cover the calibration processes when there are errors present in the measurement as well as what other mechanical errors could still exist in your system and how those could be handled. Here is a link to the absolute encoder design guidelines document so that you may review it further: https://www.ti.com.cn/cn/lit/pdf/tiduc07

Let me know if this helps address any of your system accuracy test questions, or if you have any remaining questions!

Best,

Isaac
