Can the AD797 be used as a non-inverting buffer? I followed the circuit guidance in the data-sheet (figure 37), but the circuit is oscillating at about 900 KHz. Table 6 on the data sheet lists the recommended circuit values for the follower circuit, but does not include a gain of one. I know its sometimes hard to "tame" this part. I have used it in the past but always at higher gains. My application is that I need a low noise non-inverting buffer (A=1) with a flat bandwith out to beyond 100 KHz. My source impedance is low, so the AD797 is a good choice. I also noticed that there are no closed-loop gain plots in the data-sheet?
Now I'm looking at the ADA4004. The data sheet does show the closed-loop gain (figure 19) and shows a gain = +1 plot. Would the the ADA4004 be a better choice? Maybe its less finicky to circuit layout etc?
