Applications Information 1.0 ADC104S021 OPERATION The ADC104S021 is a successive-approximation analog-to- digital converter designed around a charge-redistribution dig- ital-to-analog converter. Simplified schematics of the AD- C104S021 in both track and hold modes are shown in Figures 1, 2, respectively. In ...
