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 13 shows the output data formats for Mode 1 and 3 – 6. Figure 14 shows the output data

formats for Mode 2. Table 3 summarises the output data obtained for each format.
