55 / 78 page  Data Sheet ADATE320 THEORY OF OPERATION analog.com Rev. C | 55 of 78 Table 28 describes detailed m register and c register selection as a function of mode and range control settings. For all DAC functions, it is necessary to ensure that the respective m register and c register values are put in place first, and that the desired mode and range settings are updated prior to sending data to the DAC. It is only during the DAC write sequence that the calibration constants are selected and applied.
