Could you change the ADC reference to 2.048V ?
Then you wouldn't need an amplifier at all
You'd need lots of local C to get the noise down, but since the signal is from a pot I doubt the time constant would matter

I can't figure out how the O.P. is worrying about fractional percent resolution and accuracy with the signals coming from pots. I haven't seen many pots with fractional percent linearity, repeatability or noise. Seems like garden variety 1% parts should keep up with the pots.
