OpAmp I/O range determination from a datasheet
The front page of the data sheet tries to paint the best picture it can and on the front page for the AD8055 it says that the supply is +/- 5 volts. Look no further, this device is not suitable for +/- 2.5 volt supplies. End of story.

Look a little further if you must but on page 4 it shows this: -



You should also look at absolute max ratings too. One that can trip out is the maximum differential voltage between input pins - for this device it's +/-2.5 volts so don't go using as a comparator!!
