[sdiy] Something better than CD4066 to switch CVs?

[Tom Bugs]

Yes, DG4xxLDY is the low voltage version - DG4XXDY is the required!
(DY being SOIC version, I think)

I've used DG412 within VCOs for adding range switch and simple sync - I 
mean, you have 4 sections so you've got some options to play with.
If just wishing to switch in a cap then consider the DG417/8 which are 
single SPST (NO or NC) or the DG419 which is a single SPDT.

None are particularly cheap, but I like them a lot.
Oh, that reminds me - Coolaudio do the V411 (clone of DG411) - similar 
to DG412 but with inverted switch behaviour.
