| Abstract: | Mathematical models of digital-analog converters (DAC) based on a code-controlled divider (CCD), which takes into account the effect of the difference in the residual resistances of the closed switches and the zero-bias voltage of the operational amplifier are presented. A mathematical model of the output resistance of the CCD when it is connected in reverse in the DAC is considered. The particular fetures of the change in the individual components of the error of the DAC and of the output resistance of the CCD over the band are obtained.
