What power supplies does the AD7961 require? Does it power down?

What power supplies does the AD7961 require? Does it power down?

 

The AD7961 operates from 1.8V and 5V supplies (VDD1 = +5V, VDD2 = +1.8V, VIO =
+1.8V), dissipating only 39 mW at 5-MSPS when converting in self-clocked mode.
The power dissipation scales linearly with throughput. When powering up the
AD7961 device, first apply 1.8 V (VDD2, VIO) to the device, then ramp 5 V
(VDD1) and apply an external reference voltage. Apply the analog inputs last.

The AD7961 powers down when EN3 to EN0 = X000 and operates in snooze mode when
EN3 to EN0 = XX11 using the correct reference choice.

Refer to CN-277 or UG-581 for complete information on how to generate the
required supplies for the AD7961.
