10.13 Auxiliary DACs
The DAC1205D650 integrates two auxiliary DACs that can be used to compensate for
any offset between the DAC and the next stage in the transmission path.
Both auxiliary DACs have a resolution of 10-bit and are current sources (referenced to
ground). The settings applied to AUX_A[9:0] and AUX_B[9:0] define the offset data:
(6)
The output current depends on the auxiliary DAC data:
(7)
(8)
Table 39 “Auxiliary DAC transfer function”
shows the output current as a function of the
auxiliary DAC data.
Table 39.
Default settings are shown highlighted.
