Abstract
This disclosure includes an analog-to-digital converter (ADC) including multiple digital-to-analog converter (DAC) elements and multiple comparators, with an output of each of the comparators provided to an input of a different one of the multiple DAC elements. The ADC also includes a first voltage connection provided to each of the multiple comparators and multiple second voltage connections, with a different second voltage connection provided to each of the multiple comparators. The ADC further includes first and second resistor ladders, with the first resistor ladder configured to be switchably coupled to a first voltage supply and the second resistor ladder configured to be switchably coupled to a second voltage supply. Each of the second voltage connections is configured to be switchably coupled to a different one of the nodes in the first resistor ladder and to a different one of the nodes in the second resistor ladder.
