Offset and gain registers for each channel correct offset and gain errors. As shown in Figure 7-28, the 24-bit offset register value is subtracted from the conversion data before multiplication by the 24-bit gain register value. Data are rounded to the final resolution (16- or 24-bit) and clipped to +FS and –FS code values for the final output.
Equation 20 shows how conversion data are calibrated:
