AD8250 output voltage offset differes from reference input

Hi!

 

I have AD8250 instrumentation amplifier with +-5V supplies and with a 1,5V at the reference input pin.

The reference comes from lo impedance source and the instrumentation amplifier's supply's are correctly decoupled.

I expect 1,5V at the output when the input pins are shorted to ground but instead I get 1,7V.

What can be the cause for this?

 

With best regards,

Marek
