TIDA-01580: AFE4900

Hello,

Thanks for reaching out.

Typical two electrode configuration does not use a third wire or connection for Right Leg Drive (RLD). In such scenario, the signals coming from the electrodes are AC coupled using capacitors.

By shorting J3, the common mode voltage is provided to the inputs using a resistor divider network.
