In reply to Michael Steffes:
And actually Jon, you would use a part like the THS4131 to level shift your input to 0V centered and then only use one side of the output as a single ended in to single out DC adjustment.
Would have to set up for a gain of 2 to get a net gain of 1 if only using one side of output.
Can you explain how I would connect the op amp.
here you go Jon, see if this makes any sense,
essentially using the FDA common mode loop to do a DC coupled level shift. It produces a differential output, but you can just use one side - works well it seems. Don't know your load, but match them on each output side.

Thanks for your reply. Having looked at Michael's solution I think that should perform as I want.
