Hi all,
are there any chance to measure impedance of the bias electrode by using ADS1299. In PDF about ADS1299 they say that there is a way to detect lead-off during normal operation. I cant see how can I configure ADS1299 for lead-off detection of the bias electrode during normal operation. Also they show current source on bias electrode (ILGND_OFF[1:0). Where can I find this register? Also if I turn off bias amplifier for online lead-off detection, wher is current path closed? On the capacitive coupling through patient or somewere else?
