ADS 1298 - EEG application with active electrodes

Other Parts Discussed in Thread: INA128, ADS1298

Hi,

 

I'm am planning to use the ADS 1298 chip for EEG mesurements. I want to use active electrodes for that, something similar to the one described here: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC497047/  (at figure 6, to be more exact). Can you recommend an op.amp. for this?
I think still need an in-amp before the ads1298, I have been thinking of using the INA128 (with the + and - electrodes on it's input). If i understand corretly, i just need to connect it's output to the ads's IN1P leg, and I can connect theIN1N leg to the ground?
