ADVANCE INFORMATION
Per-channel offset and gain registers correct for offset and gain errors. As shown in Figure 7-28, the 24-bit offset correction value is subtracted from the conversion data before multiplication by the 24-bit gain correction value. Output data are rounded to the final resolution (16- or 24-bit) and clipped to +FS and –FS code values after the scaling operation.
Equation 20 shows how conversion data are calibrated:
