The ADC141S626 is a 14-bit, 50 kSPS to 250 kSPS sampling Analog-to-Digital (A/D) converter. The converter is based on a successive-approximation register architecture where the differential nature of the analog inputs is maintained from the internal track-and-hold circuits throughout the A/D converter to provide excellent common-mode signal rejection. The ADC141S626 features an external reference that can be varied from 1.0V to VA and a zero-power track mode where the ADC is consuming the minimum amount of supply current while the internal sampling capacitor is tracking the applied analog input voltage.
