ADS1298ECGFE-PDK: Channel Graphs

Part Number: ADS1298ECGFE-PDK
Other Parts Discussed in Thread: ADS1298RECGFE-PDK, ADS1298


Currently we are getting graphs of Lead I as following The 1st one is (ECG_Waveform_1.0.pdf) No.of samples against Voltage in mV. and the second one is (ECG_Waveform_2.0.pdf

) Time in Secounds against Voltage in mV. We are getting  distortion in both the graphs. How we will get standard graphs as per the graphs of Reference board(ADS1298RECGFE-PDK) output.

Our resistor setting is as per ADS1298RECGFE-PDK resistor setting.

Please help.

Thanks and Regards


  • Hi Koustubh,

    Thanks for your post. 

    The second plot looks like there's a mistake in your data processing routine. This is not caused by the ADS1298.

    The remaining noise observed on the baseline is likely power line interference (50 Hz / 60 Hz noise coupling). You will have to implement additional filtering techniques to remove this noise.
