Hi,
No, I can't think of much. Obviously it must be specified for 5 volts rail to rail operation and the input bias (and output) must "include the earth/negative rail". Some FET types may have a relatively poor (i.e. large, say > 1mV) input offset voltage which may be signficant if you're using small input voltages (e.g. less than 100 mV). Some Op-Amps may need external "stabilising" components.
If in doubt, post a link to the device in question and we may be able to see if there are any "obvious" issues in the data sheet.
Cheers, Alan.
