* The value that can be set as output data at this time is an integer. Select "1228" or "1229" as the
output data.
The analog signal corresponding to the output data contains an error as follows:
- Output data "1228" converted to: 2.9980 V
- Output data "1229" converted to: 3.0005 V
This error is a consequential error occurring when output data is obtained from an expected analog
value.
Data transfer method
It is the device buffer mode, which uses memory for conversion data storage either on the device or in
the driver.
The application output data is first stored in the device buffer (memory on the device itself or in the
driver).
When conversion starts, the device starts outputting the output data.
The device buffer can operate as FIFO or RING memory.
Device buffer mode handles conversion data by sampling count and API functions are provided to
retrieve conversion data directly as voltage values.
