[sdiy] Voltage dividers - best practice

[Justin Owen]

OK, next on the list...

My current build uses about a half dozen voltage dividers - all referencing V/2 (as in - half of voltage). Right now it's all on the breadboard - so I'm just using pairs of 10k resistors placed at the closest point to where they're needed.

When I come to laying out the PCB - would it be best practice to have individual voltage dividers providing the reference voltage at the points closest to where they're need (i.e. multiple dividers like I have now)? Or would it be better to have one reference point and have everything drawing from that? Or does it make no difference?

Secondly - regardless of what method I go for - I'm presuming that, for peace of mind, if nothing else - decoupling these voltage divider/s would be a sensible thing to do? Or again - makes no noticeable difference either way in the real world?

Cool - thanks again!
