AD9244 input span

Question asked by mapr on Sep 11, 2016

The internal reference of my AD9244 is set to 2V (Sense pin at AGND). Does this mean my input span could be 2Vp-p centered around 0V? I have a differential output with a span of 1.8Vp-p centered around 0V common coming in to VIN+ and Vin-. However, the data sheet on page 18 specified that Vin- has to be above AGND. Does this mean I have to make sure my VIN common mode has to be at 1V rather than at 0V? 

Any help would be greatly appreciated.
