Applications Information 1.0 ADC101S021 OPERATION The ADC101S021 is a successive-approximation analog-to- digital converter designed around a charge-redistribution dig- ital-to-analog converter core. Simplified schematics of the ADC101S021 in both track and hold modes are shown in Figure 3 and Figure 4, ...
