Hi Kelly,
can you show a schematic?
Have you noticed that the LMP7708 is a decompensated OPAmp and needs a minimum gain of factor ten?
Kai
It does sound like you use LMP7708 in a buffer configuration but as Kai said in order to be stable this op amp requires higher close-loop gain.
In order to stabilized decompensated op amps, you must increase the close-loop gain, Gmin, so it crosses AOL at f2 or lower frequency. In case of LMP7708 recommended min gain is 10 or higher - see below.
