Table 37.
Default settings are shown highlighted.
The coding of the fine gain adjustment is two’s complement.
When the DAC1405D650 analog output is DC connected to the next stage, the digital
offset correction can be used to adjust the common mode level at the output of the DAC. It
adds an offset at the end of the digital part, just before the DAC.
