9.4 ADS1299EEG-FE Power-Supply Recommendations
Figure 70 shows a +6V power-supply cable (not provided in the EVM kit) connected to a battery pack with
four 1.5V batteries connected in series. Connecting to a wall-powered source (provided in the EVM kit)
makes the ADS1299EEG-FE more susceptible to 50Hz/60Hz noise pickup; therefore, for best
performance, it is recommended to power the ADS1299EEG-FE with a battery source. This configuration
minimizes the amount of noise pickup seen at the digitized output of the ADS1299.
