has been completed; this occurs M clock periods after the
FDS transition to “ON”. Acquisition, Initial Data Point and
Tracking for the next integration follow automatically. The
DDC101 continues in the Tracking mode until the next FDS
command initiates the measurement of the M final data point
samples. An FDS command is needed for each integration
cycle. In the continuous integration mode, the FDS pulse
width must be less than M clock periods. If the FDS pulse
is held low past this time of M clock periods, the DDC101
will reset as for non-continuous mode (see also Figure 4).
In the continuous mode of operation, the tracking logic of
the DDC101 “remembers” the integration rate of the previ-
ous integration and begins the next integration at the rate of
the previous integration. This allows faster acquisition of the
signal for the next integration.
