Hello All,
I want to use a PIC 18F452 to do analogue to digital conversion. I know how to aquire the input using C18 or assembly, but i am not sure how to wire it up. My input voltage will be around 20VDC +- 4V, however i intend to use this through a voltage divider, so i'll convert to 2.0VDC +- 0.4V (ie. 1/10).
What would i wire to vref? I read at
that a TL341 chip (what is that?) will give 2.5V range.... this is perfect.
How would i wire up such a circuit?
