Zusammenfassung:	An analog-to-digital converter (ADC) includes a digital-to-analog converter (DAC) having a resistor network. The resistor network includes a first and second segments. The first segment includes a first switch coupled between a first supply voltage node and a first set of resistors. The second segment includes a second switch coupled between the first supply voltage node and a second set of resistors. The first segment includes a third switch coupled in series with a second resistor. The series-combination of the third switch and second resistor coupled in parallel with at least one resistor of the first set of resistors. The second segment includes a fourth switch coupled in series with a third resistor. The series-combination of the fourth switch and third resistor is coupled in parallel with at least one resistor of the second set of resistors.
