Product data sheet
10.13 Auxiliary DACs
The DAC1405D650 integrates 2 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 output current depends on the auxiliary DAC data:
