Figure 40. Quiet Zones and No-Read Zones
The device enters the conversion phase from the sampling phase when a falling edge is detected on
CONVST_QUAL. This is shown in Figure 41, Figure 42, and Figure 43.
2. Sample (acquisition) start command:
The device starts sampling from the wait state or at the end of a conversion if CONVST_QUAL is detected
as high and CS as low. This is shown in Figure 41, Figure 42, and Figure 43.
Maintaining this condition when the device has just finished a conversion (as shown in Figure 41) takes the
device immediately into the sampling phase after the conversion phase (back-to-back conversion) and hence
achieves maximum throughput. Otherwise, the device enters the wait state.
