AD8055 supply voltage ambiguity
Operating range is given on page 4 as +/-5V typical and +/-6V maximum.  The way the absolute maximum rating is shown as +13.2v doesn't matter too much (-6V to +6V is +12V total), it is 1.2V above the total supply range which is typical.

Also note that these opamps are voltage feedback (not current) although the specifications do suggest they provide similar capability to current feedback amps.


  The AD8055 (single) and AD8056 (dual) voltage feedback amplifiers offer bandwidth and slew rate typically found in current feedback amplifiers


If you want to use a 12V single supply then connect +12V to V+ and GND to V-.  There will be no -12V in this configuration.

Your other option is a split supply with +6V to V+ and -6V to V-.
