Hi,
Does TI have a gain and offset error excel calculator for isolated voltage sensing?

Yes we do!
The attached excel calculator can be used in order to calculate the expected gain and offset error. Simply input the specifications from the datasheet and hit enter to see the results!
Note that there are two tabs to the calculator, and the second tab is meant to be used with an R3' resistor on the negative input. An example of this topology can be seen below:
The calculator is currently loaded with specifications for the AMC1301-Q1, but any isolated amplifier with a differential input amplifier stage can be used.
