Preliminary data sheet
10.12 Auxiliary DACs
The DAC1408D650 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 10-bit resolution and are current sources (referenced to
ground).
The output current depends on the auxiliary DAC data:
