I want to use the AD8622 at +/-5V to drive a 10uF capacitor. Will that cause a stability problem?
To estimate the load driving capability of the AD8622, refer to Fig 30 and Fig 33 (small signal overshoot vs load capacitance) of the data sheet. Overshoot is about 40%-45% with a 0.1uF load capacitor. The AD8622 will not be able to drive 10uF of load. I have tested it in lab and it will oscillate with 10uF. There are a couple of ways to solve this problem. You can add a resistor (~50ohm) in series with the output to isolate the load cap and the op amp and thus, increase stability. This solution has its pros and cons. For more information, refer to the attached article.
