ADC buffer amp design

Hello
I'm looking for an input buffer amp design for a MAX1270 ADC.· The input analog voltage may not have the same ground on each channel or range.· My thought is to use a differential input into a summing amp, thus I think this would allow for a 0v that may be above ground.· The board will be an interface for various devices in a room.· Also,· I need to ensure a good high frequency noise rejection.· All the signals I will be measuring are mostly DC level with slow slew rates.
Thanks for any help or links that anyone can provide.
