We are analyzing a design that is using the AD598. I see in the data sheet there looks to be a section that describes the error of the position output. Total error looks to be 1.65%. In the notes are the initial error, gain drift and offset drift.
My question: Is this all due to the IC variations or do these include IC variations and external component variations. I need to know if to add additional errors due to external component variations.
As stated in note 2, the error includes only the errors of the AD598 itself.
