EEG BCI PCB Design Support
Objective: Focus ONLY on the reference, bias, and internal configuration pins of the ADS1299 (U2).
Please make the following connections:
Route the REF Connector to ADS1299 PIN 13 (SRB1).
Route ADS1299 PIN 5 (BIASOUT) to the BIAS Connector.
Connect ADS1299 PIN 6 (BIASIN) to PIN 5 (BIASOUT) using a 1MΩ resistor and a 1.5nF capacitor placed in parallel.
Connect ADS1299 PIN 12 (VREFN) to the AVSS (-5V) net.
Leave ADS1299 PIN 11 (VREFP) and PIN 44 (CLK) floating/unconnected.
