Supply question for AD9631 op-amp

Hi all,

 

Is it acceptable to connect the -Vs supply input of the AD9631 to ground (and let's say +Vs = +3.3V)?  I would like to remove a -3.3V supply from my board which has an AD9631 on it and just use ground as -Vs.  Currently, I have a 200 ohm resistor from output (pin 6) to negative input (pin 2) and the input signal on positive input (pin 3).  The input signal will now be positive going 0-2V range.

 

Will I run into problems doing this?

 

Thanks!
