Input range of ADCMP582

Hello,

 

I have a question about Table-7 of the document for EVAL-ADCMP582.

http://www.analog.com/static/imported-files/eval_boards/310187823ADCMP572_3_80_1_2EB_0.pdf

 

In the right side of Table-7 , Vp/Vn range is described as -2.5V to +2.5V.

But I think the Vp/Vn range is -2.0V to +3.0V in this condition because VCCI

and VEE are as same as table-1 of datasheet. (VCCI=+5.0V, VEE=-5.0V)

When I use the (Vp/Vn)input range as -2.5V to +2.5V, I think VCCI and VEE should be set as VCCI=+4.5V and VEE=-5.5V.

 

Is the Vp/Vn input range in Table-7 right ?

 

 

Best regards,
