Changing analog offset in ADE7758

I am currently developing a prototype board using ADE7758.

For testing, we generated an analog voltage using arduino & brought down to the range 0.25V (peak to peak). Then I supplied it to the AC voltage input pin of the ADE7758.

The ADE responded well & was able to read voltage from ADE7758.

But the issue is that my aduino generated analog voltage offset 2.5V. ie; it oscillates between 2.25V-2.75V.

Since I have followed the test circuit as in ADE7758 datasheet, this voltage never crosses zero.

At this point, am not about current measurement.
