Thank you! you really cleared the fog in my mind. Your videos are still helping people even now. May God bless you ~

Very nice series,esp. love the way you have broken it down into small videos.Thanks Matt Duff & AD !

Hi Rajan, Thanks for your feedback. We've produced many traditional whiteboard videos and decided to try a different approach. The presenter writes normally and we make adjustments in post-production.

I'm so confused what the order of this video series is?

Hi, I am deciding to use 2 × AD797AN as a buffer(configure in voltage follower) in my 47 headphone amplifier. Do I need to connect an input resistor to AD797AN positive input pin when in this application?

So confused about notation of these different gains. A is open loop, ABeta is loop gain, but what is closed loop gain?

[@jackyzou2376]

Beta is the closed loop gain.

For the whole video, I was just trying to figure out how he managed to write mirror-image.

Hi Jacky, we video recorded Matt, then in post-production, we flipped the video 180 degrees.

@@analogdevicesinc It would seem that it's not only the engineers who are brilliant at ADI! :)
