Default TLC271 replacement

Can anyone tell me what I need to do if I want to replace the TLC271 in this schematic with a opa627 instead? Dont have means to measure oscillation, so want to be absolutly sure before just replacing the opamp..

aarsoe,
Isn't this opamp used to correct offset?

Hummm - good point, so are you saying that replacing it will be worthless? (happen to have a the 627's in house anyway..)

you can find the entire circuit here:

To me this is DC correction so unless some brighter minds correct me, replacing this chip is useless soundwise.
