The coding of the fine gain adjustment is two’s complement.
10.10 Digital offset correction
When the DAC1408D650 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.
The settings applied to DAC_A_OFFSET[11:0] (register 09h; see
Table 27
“DAC_A_CFG_1 register (address 09h) bit description”
and register 0Bh; see
Table 29
“DAC_A_CFG_3 register (address 0Bh) bit description”
