The settings applied to DAC_A_GAIN_FINE[5:0] (see
Table 20 “DAC_A_Cfg_2 register
(address 0Ah) bit description”
) and to DAC_B_GAIN_FINE[5:0] (see
Table 23
“DAC_B_Cfg_2 register (address 0Dh) bit description”
) define the fine variation of the
full-scale current (see
Table 40
).

The coding of the fine gain adjustment is two’s complement.
10.11 Digital offset adjustment
When the DAC1405D750 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] (see
Table 19 “DAC_A_Cfg_1 register
(address 09h) bit description”
and
Table 21 “DAC_A_Cfg_3 register (address 0Bh) bit
description”
) and to “DAC_B_OFFSET[11:0]” (see
Table 22 “DAC_B_Cfg_1 register
(address 0Ch) bit description”
and
Table 24 “DAC_B_Cfg_3 register (address 0Eh) bit
description”
) define the range of variation of the digital offset (see
Table 41
).
