READING DATA FROM THE FIFO
The THS1206 informs the connected processor via the digital output DATA_AV (data available) that a block of conversion
values are 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 30, 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.

Figure 30. Trigger Level 1 Selected
In Figure 31, 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.

Figure 31. Trigger Level 4 Selected
In Figure 32, 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.

READ
Figure 32. Trigger Level 8 Selected
In Figure 33, 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.
CONV_CLK

Figure 33. Trigger Level 14 Selected
READ is always the logical combination of CS0, CS1, and RD.
