Check for power supply noise. Power supply noise rejection figures
given for op-amps often apply at low frequencies and noise from (e.g.)
DC-DC converters appears on the output. Are you limiting the bandwidth
of the signal out of the op-amp? That might be worth a try.
No, it is not. Having a cap over the feedback doesn't
limit the noise bandwidth. A bandwidth limit has to
be external, eg as RC following the OPAmp.
