If you have an A/D converter reading an analog voltage, with a reference voltage of 5 volts, your reading will be "referenced" to this 5 volt value.

For instance, if you input voltage is 4 volts, then you are reading 80% of your reference voltage, right? (4/5 is 80%)

The resolution, or "how well you can resolve" this reading, is described in bits. An 8-bit A/D divides up the reference voltage into... Read Compelte post
