Output data
Output data = ((Voltage - Min. range value) x Resolution) / (Max. range value - Min. range value)
The value of resolution for the 16-bit device is 65536.
The table below shows the relationship between output data and voltage in the ±10-V range.

Ex.: When 3V is output at a resolution of 16-bit in the ±10-V range
Output data

The value that can be set as output data at this time is an integer. Select "42598" or "42599" as the
output data.
The analog signal corresponding to the output data contains an error as follows:
- Output data "42598" converted to: 2.9998 V
- Output data "42598" converted to: 3.0001 V
This error is a consequential error occurring when output data is obtained from an expected analog
value.
