Need an 8-channel analog mux for weak signals (mV range)

Hi,

I'm working on 8-LEAD ECG signal acquisiiton for which I need an 8-channel analog mux to save the resources (both cost and space). But the issue is that the ECG signals are very weak (max of 1mV). So I need an analog mux that does the minimum (or no) distortion for such low voltages.

 

I have searched many analog muxes from analog devices (and some others as well), but I don't know which parameter of the specs will give information about the distortion or about handling such low voltages perfectly.

 

Input from the community will be highly appreciated.

 

Best regards,

M. Hammad Tariq
