Wil Grover (972.644.5580) from TI called this afternoon, recommending, as I had expected, the ADS1255 for my EEG project. He had some other recommendations. He recommended that I use a transimpedance amplifier rather than an instrumentation amplifier. Specifically, he suggested building one from either an IVC102, OPA129 or DDC112. I'll have to look at those. These would be connected to the scalp. Then, we would have an instrumentation ampflier, outputing a single ended output into the ADC.
