In datasheet of AD7682, Cin/Rin are written as 27pF/2.2kOhm (typ.).
1. How much is Cin/Rin variation?
2. Can it prescribe as Max/Min?
The Cin and Rin values do not vary much and we don't specify the min/max values.
The Cin and Rin values are typical as stated on the datasheet, and if there would be some changes I think, I expect to be very small because if this value will have significant change it will affect much the AD7682 performance.
I'll try to check if these values are available and get back to you.
