AD7608 supply

I am using the AD7608. The datasheet only specifies a total current of 27mA @ 5V for Vanalog & Vdrive.

Like already discussed in a former topic ( the currents can be splitted in Ianalog=22mA and IDRIVE=5mA.

Which current can be assumed if VDRIVE is 3.3V?

    Hi Alex,

    The 5mA is a rough figure that was given on the other post, with some dependencies.

    Provided that 3.3Vdrive would not vary significantly the Idrive current, I would suggest designing based on this figure for either Vdrive voltage level. Would this 5mA be a concern on your application?
