How uses the current output? Because with the application note, the output is
directly converted in voltage and after to current.

My application is very easy, I would like generated a same current into a
variable charge (NTC). Could you help me?


The max output current of the DAC is 2.5mA. You can drive any Resistive load ,
but the NTC must be of high value.(>10K)
If not, you have to use some interface circuitry to boost the current, like
that of the application note.
