Hi all,
I read several dossiers about op-amp circuiting. One mayor issue: keep every route as short as possible, especially feedback loops and decoupling. Because of the phyiscal dimensions of - for instance - the caps, you will end up in some sort of compromise. Did you ever try to 'sandwich' an opamp circuit? You could bend the pins for +V and -V upwards and place a second board from above, so you can easily use even big caps, and have signal and feeding circuitry far from another. (I cannot make printed boards at home, so I'm doing p2p.) Good idea or do I forget something here? Maybe you have other tricky (or basic) ideas for elegant wiring? Rüdiger |

I once tried something like that by standing all passive components on one wire and putting another board on top. I like the result, very compact, and you gain some more leeway in making a good layout. There's one big disadvantage: if you want to change someting afterwards, you either have to wring the component out in some way, which may damage it, or remove the upper board which is an even bigger pain.
