Ah ... look at the little ( humour ) difference between AD7376 and the XICOR X9xxx ...
One can be used ... and the other NOT here.

Hi, KB3
As the capacitor have one terminal to be grounded, you can use Mosfets like 2N7000 or BS 170 instead of the relays.
But it will introduce a small parasitic capacitor ... if it doesn't matter, that would be simpler to build.

Who says I haven't used non-proportional radios, with them ol' 45v batteries in the TX's...big ol' switches, big ol' boxes...etc.
Besides that, I've got a pilot license now. I've still got to train my arms to be a little more proportional on those crosswind landings

AD7376 - X9xxx - One can be used, the other can't.... Looks to me like both could be used.
What am I missing?


As far as using the 2N7000 to switch the cap's in and out...
Q: Even if you drive the '7000 fairly hard, it'll still have a couple of ohms across the drain-source. Won't that mess with whatever cap it's connecting into the circuit like the 4066? I know the 4066 is a lot worse and it affected my circuit.
