I am using ADG819 in one of my application.(https://www.analog.com/media/en/technical-documentation/data-sheets/adg819.pdf).

May I know what is the input capacitance of the pin marked green color.

 

hi hoy,
Only data I can find is this clip.
Look at the ADG819 LTS sub or net file and search for Cs [Off] and Co [On]

hi Hoy, @hoyyoth
Located this on the Data sheet.

I only can see the Digital Input Capacitance shows Cin = 5pF,
You said that the green color may be because the Cin is only 5pF and that is too small, so you can ignore it.
