Hello rex,

For EEG measurement I recommend evaluating the ADS1299 because it is lower noise. It also contains low-noise PGAs so that you should not require the INA333.

I will move your post to the precision data converters forum for further assistance.

Hey rex,

In agreement with Pete, I believe you should look into using the ADS1299 due to its spectacular noise performance. If you go that route, electrodes can be connected directly to the ADS1299 pins and you can amplify the signal using the internal PGAs. Is that a viable option?
