Well, you didn't say which op amp in which circuit, but here are a couple 
of precision devices for you to look at:
OPA227, OPA277, LT1055.

319 is a dual, as far as I know.

The 311 is usually fast enough, given the required cap discharge 
time.  Anything faster can just give you problems with noise spikes.

Let us know what you pick!
