    Yanamandra, 

    I'm not sure what you are asking.  Are you wanting to multiplex one source to two different analog front ends?  Are you looking for assistance on selecting and external mux like the TMUX1574?  

    Do you have a diagram that you would like help with? 

    Thank you, 

    Adam

    Yanamandra,

    Please provide a schematic and/or diagram that shows what you are doing.

    You can use a MUX in front of the ADS1292R to read multiple analog inputs, however I cannot recommend this method since there will be a delay of 4 conversions after switching the MUX due to resetting the digital filter within the device. This means that you cannot take a true 12-lead ECG reading since the data from all leads will not be read simultaneously.

    For 12 lead ECG I would recommend using both a ADS1294R and ADS1298. This thread may help: e2e.ti.com/.../665600
