The device enters the wait phase at the end of the conversion if the sample start command is not given. This
is shown in Figure 42.
Figure 42. Convert and Sample with Wait
If lower power dissipation is desired and throughput can be compromised, a nap state can be inserted in
between cycles (as shown in Figure 43). The device enters a low power (3 mA) state called nap if the end of
the conversion happens when CONVST_QUAL is low. The cost for using this special wait state is a longer
sampling time (t
acq2
) plus the nap time.
