ADS1298 Front end gain

Other Parts Discussed in Thread: ADS1298

I'm trying to use the ADS1298 for an EEG rather than an ECG but to get the best noise figure possible, I'll have to add some extra gain at the front. I was planning on using instrumentation amplifiers and feeding the single ended signal output and A/D reference voltage into the PGAs on the ADS1298. Is there a better way to go about this? I'm just worried about digital switching noise on the power lines affecting the reference voltage. Should I be using a fully differential amplifier instead of an instrumentation amplifier?
