So this a concept I have been struggling with for a long time
I found what I thought was a decent video but the issues is, every time someone tries to talk about common mode they go into some deep dark amplifier discussion. Whiping out any hope of learning what common mode is.
Here is a video I found I thought was ok
However now im confused again. Does anyone have any better resources to explain what the heck common mode voltage is.
Here is the main reason I ask. When trying to spec a part I see people always ask the question. What is the common mode range.
I don't how that question pertains to the video link I posted.
For example, I was trying to understand what is the lowest value a comparator can detect reliably.
And someone asked me, well what is the common mode voltage of the part?
So I went and looked and gave an answer they said yep you can detect down to that point.
So how do these two things connect. How does this video about common mode voltage apply to parts and this example I gave on the comparator spec?
apparently I am significantly confused here or at least feel like I am
