Conversion data are coded in two's-complement format, MSB sign bit first, 16- or 24-bit resolution. The data resolution is selected by the DATA bit of the GEN_CFG3 register. Table 7-13 lists the data scaling for the 24-bit data mode. Conversion data clips to positive and negative full-scale code values when the input signal exceeds the positive and negative full-scale range. 16-bit resolution mode rounds the data to the nearest 16-bit value.
