LMP8603Q offset voltage compensation

Other Parts Discussed in Thread: LMP8603


Figure 3 on the LMP8603 data sheet (SNOSB36D) shows the change in V_offset as a function of the common mode input voltage and the chip temperature.  For a given chip, how repeatable are these curves, and can I use them to compensate my output in software downstream of my A/D? 

To clarify, I am trying to make a small number of PCBs that have an LMP8603.  I would like to put each PCB in a temperature chamber and create those curves on a PCB by PCB basis, and then load the PCB-specific curve onto a micro processor on each PCB to compensate for temperature and common mode errors.  If I do this, will I be able to reduce the effective V_offset errors 0.2mV, or is the V_offset somewhat random over time such that there's no way to repeatably compensate for it?
