Hi,

The output voltage can be calculated by the following formula in the data sheet of the DAC7714.

Where can I find the description of the value of the maximum difference between actual and ideal?

Best regards,

Howdy Seishin,

There are a couple of error sources that affect DAC DC performance -- these error sources include INL, gain error, and offset error. These error sources are typically described in that datasheet and can be used to approximate the actual output voltage, as well as calculate the TUE (total unadjusted error) value.
