I'll find the datasheets and post them - I have one on my pc at home.I will try the capacitor, but I'd love to _understand_ what's going on as well as just fixing it. Is the cap idea what they cal a 'decoupling capacitor'? Why do we get the linkage in the first place.Thanks for everyone's help!
What it did not seem to do was 'hold' the value of the pot when the wiper was lifted if i had it connected from A1 to ground.does that make sense?
What is actually happening with this effect?
Now you seem to be suggesting that there is a possible negative effect of the high values for the pull down
what is the role of the input capacitor
