Definitions

  • Figure 7 shows a circuit diagram of multiple instances of the differential output voltage R-2R DACs of Figure 6, with the outputs connected in parallel.
  • One embodiment removes the DAC. It is not a DAC if there is no digital input. It is also not a DAC if the arrangement of resistors or the switches is not one of the known forms of analog to digital converter. Another embodiment has a circuit with a novel R-2R DAC.
