DDC112
RETRIEVAL BEFOREAND AFTERCONV
TOGGLES (CONTINUOUS MODE)
For the absolute maximum time for data retrieval, data can
be retrieved
before and after
CONV toggles. Nearly all of
T
INT
is available for data retrieval. Figure 26 illustrates how
this is done by combining the two previous methods. You
must pause the retrieval during CONV’s toggling to prevent
digital noise, as discussed previously, and finish before the
next data is ready. The maximum number of DDC112s that
can be daisy-chained together is:
For T
INT
= 500
μ
s and DCLK = 10MHz, the maximum
number of DDC112s is 119.
