>> I'm not sure if Seb is reading this - but the one query I have about his S&H circuit is that there doesn't seem to be any switching/sampling part to it. The Paia Fatman S&H uses a 4016 switched by the micro but Seb's Mux output seems to go straight into the S&H cap/op amp combo.

>You did read the datasheet for the MAX306 didn't you?  All explained there - note especially the EN pin.

Thankfully, asking an embarrassing question is a small price to pay for learning something.
