The Offset and Gain Calibration Spans are defined as the range of offset and gain errors that the AD7856 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.
