AO-1616L-LPE, AO-1608L-LPE

Ring format
Use ring format if you wish to output a repeated pattern like that shown below.

When using ring format, write the data for one complete cycle of the output waveform before

starting operation.

You cannot write to the memory during its operation of analog output.
DA conversion data is output continuously in the sequence in which the ring format data is stored.

Although the figure shows a single analog output channel, output from multiple channels is also
possible.

Repeat

You can specify a repeat count to perform sampling for a specified number of times.

Output Data

Analog output as Data0 - DataN

Time

Data0

Data1 Data2

Data3

Data4
