AD8226 gain error

Hi all.

I'm trying set up an amplifier by AD8226. For basic test I tried a simple voltage divider as input differential voltage. However, my try failed because output voltage is not what I expected!

Here is the schematic:


Input voltage is about 6mv and RG is 50 ohms 5% and according to the datasheet output voltage should be about 1000×6mv = 6v

But output voltage is about 1.4 volt.

Thank you in advance for any help, it is greatly appreciated!
