R-2r dac theory
WebR-2R Ladder DAC The R-2R Ladder DAC overcomes the disadvantages of a binary weighted resistor DAC. As the name suggests, R-2R Ladder DAC produces an analog output, which is almost equal to the digital (binary) input by using a R-2R ladder network in the inverting adder circuit. The circuit diagram of a 3-bit R-2R Ladder DAC is shown in the ... Web∆Σ DACs utilize a different approach for obtaining dynamic range performance compared to R-2R DACs. The in-band (audio band) quantization noise is reduced by delta-sigma modulation and by oversampling the input spectrum at a rate much greater than for R-2R DACs. This noise-shaping performance is given by the order of the modulator as well
