Computing Aggregate Sample Rates

The sample rate is dependent on the number of channels on each ADC. Refer to Figure 2-4 to
determine how each channel is connected. For a given ADC conversion rate or timing mode, you
can calculate the maximum sample rate using the following equation:
Max Samp Rate
Table 2-3 shows the distribution of channels sampled by each ADC.
