What effect does changing the Voltage reference for a A/D converter have on each bit? Ie, if our reference voltage is 5V, and we have a 10 bit A/D, that means there are 1024 Different levels it can measure, and each bit is 4.88 mV. If we decrease Vref, does this increase Resolution and allow us to measure smaller signals, and if so, at what cost (ie tradeoffs)?
