Hi,
I'm wondering if there is any opamp that would be happy being powered with 3.3v. I'm using 3.3 to power a dspic, and as I need to add some signal conditioning/filtering, I was wondering if I could power the opamps with the same voltage. This would make my life easier.... :)

You're using a 3v3 power supply, not a regulator? Or are you worried about an op-amp on 5/9v giving out more than the PIC can take?
Some examples:
TI LMV931..4, LMV722
AD8506
Microchip MCP6001..4 - available also in standard TH packages.

I'm using a regulator, but if I can simplify and use 3.3v everywhere I ensure I will never feed more than 3.3 to the PIC and simplify a little.

ok, well remember to watch your grounding. :)
