PRODUCTION DATA.
The full-scale calibration is a 24-bit word, composed of three 8-bit registers, as shown in Table 19. The full-scale calibration value is 24-bit, straight offset binary, normalized to 1 at code 400000h. Table 17 summarizes the scaling of the full-scale register. A register value of 400000h (default value) has no gain correction (gain = 1). While the gain calibration register value corrects gain errors greater than 1 (gain correction <1), the full-scale range of the analog inputs cannot be exceeded to avoid input overload.
