AD8221BR Multisim Model

Hi all,

     AD's spec sheet for the AD8221BR claims that it can be used with a single or dual power supply.  I tried modeling a very simple DC circuit using a single source in Multisim (using Multisim's built in AD8221BR model), but it doesn't work correctly (output never changes from around 900mA) unless I use a dual source.  Does anyone know if the model can be adjusted to work off a single source?  I have some samples on order and I hope that I didn't get the wrong ones.  My design will only use a single source.  If the model is indicative of what the device really does, I may have to choose a different in-amp...

 

Thanks

Dario
