3: why does your max output HAVE to be 5V? If you are measuring it you can scale your measurement to suit.

hope so your shortlisted op amp list will be much more useful . i will try from that list.

because 0v to 4.9v variation voltage will give broad range of a/d conversion data i can get . measurement sequence much more precise.
