OUTPUT DATA FORMAT
The digital data output from the ADC is available to the user in 4-bit wide multiplexed. Latency of
valid output data with respect to VSMP is programmable by writing to control bits DEL[1:0]. The
latency for each mode is shown in the Operating Mode Timing Diagrams section.
Figure 10 shows the output data formats for Mode 1 and 3 – 6. Figure 11 shows the output data
formats for Mode 2. Table 2 summarises the output data obtained for each format.
