Hi Ryan, Thanks for the experiment.... I was thinking that at 50-60 Hz of common mode noise, we had a better inversion of the feedback loop, so we could compensate the common mode noise completely. It's like if the bias feedback lags the common mode sigal a lot. If I want to cancel most of the common mode noise in differential,... What should be the gain "goal" if I use 4 electrodes only (2 channels in differential) ? Globally a gain of "1" if I don't want to overcompensate ? The evaluation kit has a 0.01uF capacitor on the schematic but the datasheet of the ADS specify a 1.5 nF. Should I use a lower capacitor to minimise the lag ?
