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 choose the configuration, select device, and specify values for the input structure to see the results!
Note that there are five tabs to the calculator.
Please note that when using a device with low input impedance for voltage sensing, the "Differential with R3' " configuration should be used to cancel the offset error. An example of this implementation can be seen below and further details can be found in section 9.2.2 Isolated Voltage Sensing of the AMC1301-Q1 datasheet.
