Dynamic range AD8338 single-ended input

I am using an AD8338 at the core of my product design.  My first version drives it single ended.  I suspect that I am not getting anywhere near 80 dB (that is a lot!) of dynamic range.  I am not particularly sensitive to distortion.  When operating with single ended input do I lose a lot of dynamic range?  Might the BW change significantly with the gain?  I am designing the second revision of my product and wondering whether it pays to convert the signal to differential ahead of the AD8338.
