ADS8684: Calibration, different ranges

Hi,

We use the ADS8684 in one of our designs. We need to fullfill a 0.1% accuracy for all of the analog inputs and all the ranges.
So we plan to calibrate the inputs in software.

We use additional 1kOhm resistors on AIN_xP and AIN_xGND pins.

Do we have to calibrate all the ranges with different correction values or does the big part of the offset and gain error stays the same when switching the range?

Thanks and best regards,

Patrick
