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 all modes. Table 2 summarises the output data obtained

for each format.
