I have a new project where I'm taking an old monitoring device I designed years ago, and updating it to the modern age. I've been out of the loop for so long that I have no visibility on this type of device. It's just going to read some outputs from current monitors (0-3ish VDC) and convert them to be sent to a DCS.

What does Poal have? 12 bit may work, but I'd like some decent resolution.
