DRV8243-Q1: DRV8243-Q1

Hello,

in the DRV8243 datasheet, the current measurement accuracy is specified as follows:

In the low current range, the accuracy is specified as -50% and +50%.
I understand that in the worst case the accuracy can be max +50% or min -50%, but it doesn't have to be, right? Can the accuracy in this range be better?

Why is such a large range given? What does it depend on?

Thanks

Best regardes
