TAG FEATURE
The TAG feature allows the data from multiple ADS8507 converters to be read on a single serial line. The
converters are cascaded together using the DATA pins as outputs and the TAG pins as inputs as illustrated in
Figure 40
. The DATA pin of the last converter drives the processor's serial data input. Data is then shifted
through each converter, synchronous to the externally supplied data clock, onto the serial data line. The internal
clock cannot be used for this configuration.
