Ultralow Crosstalk Between DACs ( 1GО©)
when all eight DACs are powered down.
Normal operation can be resumed by executing any
command which includes a DAC update, as shown in
Table 1. The selected DAC is powered up as its voltage
output is updated.
There is an initial delay as the DAC powers up before it
begins its usual settling behavior. If less than eight DACs
are in a powered-down state prior to the update command,
the power-up delay is 5Ојs. If, on the other hand, all eight
DACs are powered down, then the master bias generation circuit is also disabled and must be restarted. In this …
