Functional Description The ADC161S626 is a 16-bit, 50 kSPS to 250 kSPS sampling Analog-to-Digital (A/D) converter. The converter uses a suc- cessive approximation register (SAR) architecture based up- on capacitive redistribution containing an inherent sample- and-hold function. The differential nature ...
