Buffers?

[Milotic]

Hi guys.

I'm currently wanting to build a IC buffer, but don't know which one. 
There is the AMZ one and the GGG one.  The GGG one is a very simple one and only uses one Op-amp, but the AMZ one uses two.  Just wondering if there is any noticeable differences between the two and which one would you recommend?

Hi
I would suggest checking this link

Its on AMZ as well with only one singel OP-amp. I often use the one with voltage divider for low parts count

Personally, I would stick with the single opamp config, especially if you use an opamp with only fair offset voltage or noise specs. Otherwise, odds are you cannot tell the difference between the two designs.

Thanks for the link solderman.  A good read at 2am.
I think i might stick to the single opamp buffer atm, but later, i might build different types of buffers and do an a/b testing to compare and decide

Thanks..
