... Capacitance at the output of an amplifier creates a delay within the feedback path that, if within the bandwidth of the loop, can create excessive ringing and oscillation. The ADA4897-1/ADA4896-2 show the most peaking at a gain of +2, as demonstrated in Figure 8. Figure 48.

... C limiting the magnitude of the gain is the output swing and drive capability of the op amp selected for the I-to-V converter, in this example, the ADA4896-2/ADA4897-1. Because any amplifier has limited drive capability, there is a finite number of channels that can be summed. ...

... POWER SUPPLY BYPASSING Power supply bypassing is a critical aspect in the performance of the ADA4896-2/ADA4897-1. A parallel connection of capac- itors from each of the power supply pins to ground works best. Smaller value capacitors offer better high frequency response, whereas larger value electrolytics offer better low frequency performance ...
