ADS1298 offset correction

Is there a possibility to get rid of the offset without digital calculation? Is there a hardware solution possible?

How are you normally cancelling the offset?

Hi Melanie,

Are you DC or AC coupling the inputs? The RLDOUT can set the DC bias point and mitigate some of the offset voltages induced by bias currents and large cable impedance.

Hello Ryan,

I already use the RLD. The input electrodes are connected to my body, as well as the RLD. But still got Offset. What else can I do?
