AD9742 output buffer


I'm working with AD9742 DAC at 48Msps with full-scale output set to 20mA. Previously our design used 50ohm resistors as current-to-voltage converter followed by Op-Amp buffers. Currently we're exploring to feed the DAC output into Op-Amp summing junctions directly and use the Op-Amp as current-to-voltage converter.The Op-Amp output will be biased to 4V common-mode and RFB=150ohm. We're not sure whether AD9742 can drive such load ?  (see attached image)
