[sdiy] OP291 op-amp

[tpaddock at seanet.com]

Any opinions on Analog Devices OP291 (OP191, OP491) op-amp?
I'm looking for a rail-rail single 5V supply op-amp that 
will do a few milliamps and get fairy close to the rails.
Mostly for CV and maybe some audio frequencies, 
but I don't need ultra hi-fi.
They would be for kind of a 'miscellaneous sensor thing' 
to 'music thing' interface.
We use them here at work, so somebody must like them. 
I know that's pretty vague, but that's where I'm at.

Anything to watch out for? 

Thanks,
