I plan to use the OP97F in an application using a single 5V supply, but all of its parameters are listed for +/-15V supply. There's a noise density graph showing it's valid from +/-2V to +/-15V but I'm not sure I trust that.

Am I right in being skeptical?

Noise in most circuits depends on bias current in the critical components. It is easy to make bias currents quite independent of supply voltage with an internal current regulator.

There is no reason to be sceptical.
