OUTPUT FORMATS

The digital data output from the ADC is available in a 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 is shown

in the Operating Mode Timing Diagrams section.

Figure 11 shows the output data formats for all modes. Table 2 summarises the output data obtained

for each format.
