DC Component in ADS1299

Other Parts Discussed in Thread: ADS1299

Hello,

I am working on EEG acquisition using ADS1299 for MRCP. For this purpose I need to retain the DC component of the EEG signal. So the question is if I use ADS1299 will it retain the DC component in EEG signal or will it corrupt the DC component?

Regards.

    Hey Qamar,

    There is no high pass filter on the ADS1299 so the DC information will be retained. In fact, one of the benefits to using such a high resolution ADC is that you can study very small signals without losing the DC voltage on which those signals rest.
