Fixed Voltage Reference

It isn't any more complicated than that.

Thanks Charles.

I just miss the understanding of the measurement process or principle.

Is it (my thinking):
- I have a precise voltage reference, let's say 4,096Volts
- I sample it 10 bits (= 1023 samples)
- Each sample is 4,096V / 1023 = 0,004V
- I read the ADC I will measure on i.e. a battery, and convert it to the voltage I want to know.

Is it "it"?
