I am using an AD8628 as a voltage follower to buffer a d.c. voltage and drive a load of 100nF and 2.2k parallel resistor.
As this is quite a large capacitive load I added a series resistor at the op-amp output with the negative feedback taken after the resistor. In this configuration the output oscillates. If I swap to an AD8029 op-amp there is no oscillation. I would like to use the AD8628 as it has a much lower offset. Any ideas ?
