reading data from the FIFO
The THS12082 informs the connected processor via the digital output DATA_AV (data available) that a block
of conversion values is ready to be read. The block size to be read is always equal to the setting of the trigger
level. The selectable trigger levels depend on the number of selected analog input channels. For example, when
choosing one analog input, a trigger level of 1, 4, 8, and 14 can be selected. The following figures demonstrate
the principle of reading the data.
In Figure 5, a trigger level of 1 is selected. The control signal DATA_AV is set to an active low pulse. This means
that the connected processor has the task to read 1 value from the ADC after every DATA_AV low pulse.

In Figure 6, a trigger level of 4 is selected. The control signal DATA_AV is set to an active low pulse. This means
that the connected processor has the task to read 4 values from the ADC after every DATA_AV low pulse.

In Figure 7, a trigger level of 8 is selected. The control signal DATA_AV is set to an active low pulse. This means
that the connected processor has the task to read 8 values from the ADC after every DATA_AV low pulse.

Figure 7. Trigger Level 8 Selected
In Figure 8, a trigger level of 14 is selected. The control signal DATA_AV is set to an active low pulse. This means
that the connected processor has the task to read 14 values from the ADC after every DATA_AV low pulse.
