Part Number: ADS1298

Hello TI support team,

For my projeckt i am using the ADS1298ECG-FE to get ECG signals from my body. So far i've got results but i have also a few questions related on the look of my ecg. i am trying to plot the raw data from ADC by Excel. Firstly the test signal looks right with amplitide and frequency when the date rate is set 500SPS. Secondly i got these ECG signals, which seem to look right, but my questions are:

1/ why do LEAD I and LEAD II have amplitudes of more than 15 mV instead of 1 mV (as required)?

2/ why are the SQRT peaks so hard to see? do we actually need some extra filter to plot these better?
