One of the features of the DS Analog-to-Digital converters like the ADS1211 and ADS1213, is the four channel, multiplexed input. This feature allows for the chip user to individually digitize up to four separate differential signals. This advantage can be useful in process control environments as long as the user understands the issues of latency associated with DS converters. This application note illustrates the topology of the DS converter, explains the phenomenon of latency in DS converters and shows its affects on the accuracy of the digital output of the converter. The Demo Board, DEM-ADS1210/11, is configured in such a manner to show this behavior.
