PRODUCTION DATA
The full-scale calibration word is 24 bits consisting of three 8-bit registers. The full-scale calibration value is straight binary and normalized to unity-gain at value = 400000h. Table 9-9 lists register values for selected gain factors. Gain errors greater than unity are corrected by full-scale values less than 400000h. Although the calibration registers provide a wide range of possible values, the input signal must not exceed ±106% of the precalibrated input range; otherwise the ADC is overranged.
