The datasheet implies you power both VDD and VLOGIC at the same time. In the Applications Information section of the datasheet, Figure 47 on page 25 does not show any gating or power sequence control. Also, all AC and Timing Characteristics specs defined in the datasheet state VDD = 2.7 V to 5.5 V, 1.8 V ≤ VLOGIC ≤ 5.5 V.
Is there any sequence required? My customer wants to know:
Does this mean we could apply VLOGIC only and configure the DAC … and then apply VDD sometime later?
