WebA delta-sigma ADC is a one -bit converter that uses oversampling implemented with a 1 -bit ADC, a 1 -bit DAC and an integrator to resolve the analog voltage into a digital equivalent. The basic conversi on element of any converter must be more accurate than the required measurement. A 1 -bit ADC is as linear as we can make because there WebThis is an impractical filter to design and build. However, if an oversampled delta-sigma ADC is used, then the Nyquist frequency goes up to one-half the oversampled sample rate. A typical choice might be 64x oversampling, in which case the ADC will sample at 2.8224 MHz. Then the Nyquist frequency is 1.4112 MHz.
