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.
