Harry,
Many thanks for your reply. At the moment we plan to build 4 of these boards. We might order one first and test the overshoot and oscillatory behaviour as you suggest. In any case, how could this behaviour be lessened?
Regarding the GBP, should the overshoot be larger when the desired bandwidth is much smaller than the GBP? i.e. if I use the AD8618 I should expect more oscillations than if I use the AD8604?
