The fastest method to perform sequential conversions
with the aux-ADC is by sending consecutive com-
mands setting AD10 = 1, AD0 = 1. With this sequence
the
CS/WAKE falling edge shifts data from the previous
conversion on to DOUT and the rising edge of
CS/WAKE loads the next conversion command at DIN.
Allow enough time for each conversion to complete
before sending the next conversion command. See
Figure 8 for single and continuous conversion examples.
