    Hi,
    
 
    I need to convert a base-band differential input to a single-ended output, bandwidth of 4 GHz. ADA4960-1 is a fully differential amplifier, so I assume I can terminate one of the differential outputs to create a differential input to single-output buffer amplifier, but the datasheet only shows the opposite case: single ended input to differential output. Will I be able to use this part for differential in to single out? If not, is there another part that would work?
    
 
    Thank you,
    
 
    Erin

      Hi Erin,
      
 
      Sorry for the late reply. For your first question, Yes you may use ada4960-1 as single-ended-output, but keep in mind that if you'll use ada4960-1 as single-ended-output you will sacrifice the gain. The resulting gain will be the half of the stage with differentil output. In order to fix that, may i suggest to use a differential to single-ended converter. But must not connect the terminated output to ground. For the second question, i am still looking for a good replacement but currently ada4960-1 is the only op-amp fitted for your 4GHz requirement.
      
 
      Thank You,
