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?
