Part Number:ADS1294
Hi Greeting~
I'd like to check some application issue with the our ADS1294.
Our customer who use it to detect the skin impedance of human body.
If we use the various resistor to simulate the skin impedance between IN1P & IN1N, here is some issue found from customer feedback
1. the impedance >30M ohm, Lead-off detected, ECG RAW data (DOUT) = 0, it works OK
2. >8M ohm and <30M ohm, lead-off non detected, but ECG RAW data (DOUT) works abnormal.
3. <8M ohm, Lead-off detected, ECG RAW data (DOUT) works OK.
Our customer would like to know, is there any relative between impedance changing and DOUT output?
such as impedance changed effect the DOUT (0 & 1 ) status?
If any unclear parts, please let me know freely.
B & R
