 		Hi all.
As I intend to use this cheap micro for my IN-9 dual bargraph project, the A-D has to work.

My plan is to use an HV853 (HV850=not enough) with a custom diode bridge to get +/-90V which should be adequate.
I found Link2 which suggests that
the A-D can be a little squirrely to get working, including the tendency to glitch due to power variations.

Also found Link2
Seems that cathode poisoning is an issue and can result in unstable glow.

Any ideas please?
