Electrodermal Activity Reference

Hello,

Is there a reference schematic for the ADI watch GEN II?

I see this article referencing the use of the AD7689BCBZ to capture electrodermal activity. The resulting data looks exactly like what I want to capture. 

https://www.analog.com/en/technical-articles/design-development-and-evaluation-of-a-system-to-obtain-electrodermal-activity.html

The article has block diagrams, but doesn't give values for the low pass filter or other systems.

I was told previously to email adas@analog.com but I have yet to receive a response and it has been over 2 weeks. Is there a different email I can use to know I'm not getting blocked by a Spam filter?

Thanks!
