Pot jitters during ADC capture

[Demon]

I'm looking at this post:

I have 3 slide pots, so I found a quad op-amp OPA4314 at JLCPCB:

Interesting stuff. This never came up in my research to debounce a pot. They quickly lose me when they talk about frequencies and Nyquist. I'm assuming this relates with audio. I'm just sampling a pot and wouldn't know how to tweak that R/C combo.

The R/C combo here is WAAAAY lower:

Found an explanation on how to chose the R/C combo between a buffer and ADC here:

It points to a TI note that suggests 100R/1nF for the OPAx365 (in the image). I'm assuming this is an excellent starting point; TI describes it as "ideal for driving sampling analog-to-digital converters (ADCs)".

Only available in single and dual, but still relatively cheap (from what I expected, I'm just happy it's available at JLCPCB).
