DRV8811: Indexer

Part Number: DRV8811

Hi Expert,

The step angle of the step#2  for 1/8step  is 11.325 in datasheet table2 .

Is it typo? I think, it is 11.25 from around values.

Also, which is correct actual behavior?

1) Actually, outputs will be set Aout=98% and Bout=20% by device control. As result, the actual angle will be tan^-1(20% / 98%) = 11.53 degrees.

2) Actually, outputs will be set Aout=cos (11.325 degrees) = 98.05..% and Bout=sin (11.325 degrees) = 19.63..% for  the angle 11.325 degrees(or 11.25degrees, if it is typo).

(Bold : datasheet values)

Thanks
