ADA4571, min and max pitch between two poles when linear config.

Hi,

Regarding to AMR angle sensor ADA4571 when used in linear configuration, I would like to know,

a) Minimum and Maximum pitch between a north and south pole which available to be used.

b) Accuracy data when used above minimum and maximum putch in above question a).

I have attached following picture of image written on white board to avoid misreadings.

⊿Lp is the pitch I'm asking. ⊿Lz is distance between sensor and the magnet.

Regards,
