Abstract: A multi-string DAC is described and comprises at least two DAC stages. Each DAC stage comprises a string of impedance elements and a switching network. In one configuration, the DAC comprises a first and second switching network, the second switching network providing multiple switched paths which compensate for impedance effects of the second string and provides multiple state changes at the output node of the DAC.
