I am almost done building this:
http://www.musicfromouterspace.com/analogsynth/cvdistributor.html
But I am putting 3 of these circuits on one board, to split 3 different CV voltage types (Hz/volt, gate, and trigger), needed for my diy modular.
QUESTION:
The PSU input caps...are listed for the one TL084. What if I'm feeding 3 chips? (+/- 12v)
Do I need to duplicate (add) the caps (and same values) before each chip's power pins? .....or is the one input set enough, and then power is distributed to all three TL084's.
I have a hunch I'll need to increase the 1uf to be higher if it's feeding 3 chips.. I'm sure there is some equation that will tell me, but I'm guessing 10uf might be ok?
(or would there be one set of 'lytics, and 0.1 bypass caps on every chip?)
The 2 datasheets I have make no mention of PSU input caps.
--------------------
'NOTHER Q:
What would I do for "protection".....diodes somewhere?,,,,after all, I am DIY'ing this, and could foresee a CV short, now and then.
