Hi Taki,

Each design will be different and will lead to different offset errors, gain errors, magnetic gain uT/A these will then impact your maximum and minimum current you can measure. The DRV421 System Parameter Calculator will help. It is located in the software section of the DRV421 product folder/Tools and Software.
