Some of the better commercial analog switches have a charge injection of < =
1pC.
To get a 100nV of disturbance implies a load capacitance of 5-10uF.
So if your source impedance is 1K you'd have a bandwidth of maybe 30Hz, whi=
ch might be limiting.

I was hoping to find a clever trick that I'd overlooked.=20
