The R-2R Ladder DAC (Digital-to-Analogue Converter) uses an R-2R ladder network within the inverting adder circuit to deliver an analogue output that is almost equal to the digital (binary) input. Since the R-2R Ladder DAC uses R and 2R resistors, the development of highly accurate resistors becomes easier. This is an advanced DAC system that efficiently overcomes the limitations of the traditional binary-weighted resistor DAC. If the digital inputs contain more bits, an apt number of additional R-2R resistors are added to the system. Due to these advantages, the R-2R Ladder DAC is considered to be superior to the binary-weighted resistor DAC.
