With an active electrode, it should be good enough. After all, we are talking about hobby-grade results.

The Olimex ones are 10-bit (supporting both active and passive electrodes), while it's claimed[0] that 12-bit resolution is sufficient for EEG.

However, it's worth noting that there are obvious advantages to the higher resolution.

EEG in microvolts, if ADC 12 bits, then reference for ADC should be in millivolts


He mentions active probes. Active probes have amplification.

As his link makes clear, your ADC just needs enough resolution to measure the signal when the (amplified) offset voltages don't saturate it.


yes, I told about digital EEG device from this website. To clarify analog device, I need a little more time
