AD5791 Reference Buffer Opamps

The data sheet and reference designs recommend the AD8676 for voltage reference buffers.  I would like to use an opamp that draws less supply current than the 3.4mA max of the AD8676.  The ADA4077-2 looks to have similar performance specs, and draws only 0.5mA.  The DC specs of the ADA4077-2 are fine for my application.  But it has a slightly lower bw than the AD8676; 4MHz vs. 10MHz.  Can anyone comment if I would be risking settling time or any other performance specs by using the ADA4077?
