Default Opamp for A/D input stage

I am working on an A/D converter (to be used in a DIY harddisk recorder). The schematic can be seen here:


I would like some opamp suggestions (I don't plan to use 1458s ;-). The opamp has to run on 5V, and it has to have rail-to-rail inputs and outputs. It should also have overvoltage protection on the inputs - and sound good of course :-)

The types that look best so far are the TI/BB OPA2340 and OPA2350. Has anybody tried those? Are there other types I should look at?

Any other circuit improvement suggestions?

Best regards,

Mikkel C. Simonsen
