Part Number: ADS1294R

Tool/software:

Hello,

I am developing an ECG system baads1294R.pdfsed on the ADS1294R, implementing dry electrode ECG acquisition, respiration measurement, and pacemaker detection.

It will be great if you could support me by reviewing my schematic.

Thank you in advance for your help.

Best regards,

Pierrick

    Hello Patrick,

    Thank you for your post. 

    The schematic looks mostly correct! Just a couple comments:

    1. I believe there is just a typo in the net names for LA and RA following the low-pass filters. Should "LAF_RLD" be renamed to just "LAF"? Same question for "RAF_RLD."
    2. There should not be a connection from RLDOUT to RLDREF. If used, that would create positive feedback around the RLD amplifier.

    Regards,

    Ryan
