dynamic range of ADS7828
ADS7828 is a 12-bit A/D converter with Vref = 4.096 V set externally through a voltage reference, REF5040, on the CaR board. Hence, it can measure a signal with an accuracy no better than Vref/2 12 = 1 mV. Often the dynamic range of the measured signals is much lower (for CLICpix2 0-1.2V) so we could have much better accuracy if Vref was dynamically configurable.
