AD7175-2 Eval Software

Hi,

 

I am trying to run the evel software for the AD7175-2. When the AVSS is set to 0V, AVDD1 and AVDD2 are set to 5V, the software simulator will work ok.

 

But when using negative value for AVSS, e.g. -2.5 V, and AVDD1 & AVDD2 are equal to 2.5V an error happen as shown in picture. (Values satisfy the datasheet specifications)

 

What voltages ADVV1 and AVVD 2 should use to make it run with -2.5V AVSS?
