ADS1291: single lead ecg input impedance

HECTOR
Intellectual 536 points
Part Number: ADS1291

Hello evryone 

I want to measure the input impedance of my ECG circuit using ADS1291 without  RLD . 

how to meausre it ? 

or how can I apply the test in the standart 60601-2-27-201.12.1.101.3 knowing there is NO  RLD electrode? 

thank you in advanced

    Hi Hector,

    The input impedance specification listed in the ADS1291 datasheet is primarily input impedance without external circuitry. For the input impedance of the complete system design, you will need to conform to the testing procedure described in the standard certification documentation.

    Please do a search on this E2E forum, as there are a few similar posts regarding this topic. You can find some of these posts listed under the "Similar topics" section to the right panel of this window.

    Thanks
