AD598 Error or Tolerance

Good Day.

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.
