    Hi,
    
 
    Can these amplifiers be powered from a single +12V power supply. The datasheet only shows +/-5 V and 5V; however the max. power supply is set to +12.6 V in the datasheet.
    
 
    Or, when operation between +/- 5V is only feasible, can I use a RF transformer at the output to have 0-10V signal swing (I want to use the devices as a pulse amplifier into 50 ohm coax with source and end termination with 5V levels at the load; pulses can be as short as 10 ns).
    
 
    Thanks for your help,
    
 
    Best regards

      These amplifiers would work at 12V single supply. Although performance of this part is not specified on this supply, you could always estimate using the specifications defined at + 5V and 5V supply. For a 5V: 10 ns pulse, AD8009 would be a better choice for it has a higher slew rate than AD8000.
      
 
      Regards.

      Hi,
      
 
      Yes, the AD8000 can operate from 4.5V to 12V in single supply configuration and from +/-2.25V and +/-6V in dual supply configuration. However, the datasheet spec table guarantees only the part operation on +/-5V and +5V while the abs max power supply of +12.6V tells that if you exceed that value we would not be able to guarantee that the part will work beyond that.
