Howdy,
As a minor feature in a gamma scintillator I'm building, I would like to provide a battery check function. The values may seem funky but they are a function of certain design points. I've muddled together a theoretical circuit to do this, but if people could look it over and let me know a couple things, I would appreciate it. I need to know if:
1) Will this work?
2) Is there an easier/better way of doing this?
3) It would be nice to do this without a negative ref...
Basically, three different key battery voltage levels provide three distinct output currents to a 50uA wiggle stick, which sports a pre-existing scale which makes sense what I'm doing.
thanks,
