The offset and gain calibration spans are defined as the range of offset and gain errors that the AD7859/AD7859L can calibrate. Note also that these are voltage spans
and are not absolute voltages (i.e., the allowable system offset voltage presented at AIN(+) for the system offset error to be adjusted out will be AIN(–)

and the allowable system full-scale voltage applied between AIN(+) and AIN(–) for the system full-scale voltage error to be adjusted out will be V

This is explained in more detail in the calibration section of the data sheet.
