Hey Guys. I am looking to design a rather simple circuit with an LDR where I can adjust the span (gain) and set a minimum voltage (offset).
This circuit is gonna be supplied by a single power supply, 0v and 5v.

Now I need help choosing the right op-amps for this circuit.
They have to be rail to rail and run with a single psu.

Now there are alot of these opamps out there, but does any of you have experience with some good ones?
Oh and also, they have to be rather cheap, but not so cheap they're crap :)
 

Take a look at the FAN4174. It is cheap, rail to rail I/O and works from 2.7 to 5.5V.
 

Awesome, thank you very much, they look pretty good. Gonna go for the FAN4274 though.
Can't wait to get on it, I am using some TL082 which i acting up weird when I'm not giving them positive and negative power, but only positive and 0v :)
