AD2S1210 Vdrive power

I am interfacing with an msp430 and need to use vdrive  @3.3v. My problem is that the logic supply rises to 3.8v when the vdrive pin is connected to logic supply. There are no application notes regarding supply sequencing that I have found. I have an evaluation board but the supplied schematic does not match the layout so its not much help.

    I'm assuming you are going to be using the pin headers to bring your signals over from the MSP430 board including your power and ground.   If so I would recommend removing the ADG3308's as the SDP connector side will be floating and this could cause you a headache.  

    I would then bring the power in through LK703.
