Hi, it's me again, we used the ADS1298 to capture ECG signal and found it worked unstabitily, because we make the PCB ourselves, and our drive code is verification in the ADS1X98ECG-FE Rev ,so we doubt something is wrong in our PCB. In the ADS1298ECG-FE user's guide ,on page 48, figure 39, the pin 24(VREFP) and pin28(VCAP1) ，the PCB route is widen used the metal-clad, is it necessary? is the current though these pin large and we have to broaden the PCB trace wide?
