Re: Can I do this with a uProcessor?

Like fet switches ? It's 'charge injection' usually. Jfets don't exhibit
this effect like CMOS swiches, although there is another way they can click

this can be reduced by driving them carefully. Do you recall these were the
type I originally recommended ?


I've been thinking about this JFET idea again, as well. Is it possible to
configure JFETs to work like a relay though, or would I use them to switch
the signal to ground (if the latter, I'm back to the 'fair amount of
rewiring' stage...)?

Yes you can use jfets in series with the signal (like a relay as you put it) as
well as to switch to ground so there's no problem there.

Just remind me what voltages you have available.
