Can someone recommend a rail to rail op amp please? i have found a couple online but they are a little expensive.

For that we need to know, at a minimum, your voltage, max frequency, and input offset requirements?

The voltage of my circuit is 5V, max frequency is 1 Hz and i don't know about input offset requirement

 

Oh and it has to be a dual device.

 

ok i am going for the TLV2462

All good!

 

MCP6476 If you do SMD watch out for the pinout. There are options.
MCP6002

 

I was going to recommend MCP6002, so I guess I will second it.
