Abstract
Using only one R2R network, driven by a digital logic, it is possible to implement both a D/A and A/D converter, An existing stabilized voltage V.sub.cc is used instead of a separate reference voltage source. The D/A and A/D converter is calibrated with this voltage and an operational amplifier circuited as a comparator. Starting with the known voltage value V.sub.cc and the assigned bit combination, it is possible to measure analog voltages from analog voltage sources using further operational amplifiers circuited as comparators.
