To clarify the resolution, I will show you how to calculate A-D converter steps.
The calculation goes like this with only two variables to change.
A-D mV steps = Voltage range Ã· Bit resolution
Now, you will need to compute the bit resolution like this: 2x10^n where n=bit resolution. Next you will need to compute the voltage range. A Â±500mV range covers -500mV to +500mV, a range of 1000mV.
So the calculation now looks like this:
3.9mV = 1000mV Ã· 256 (2x10^8)
Hope this makes sense.
