Note 1) Under the condition of output load 220Ω, IREF pin with 6.8kΩ, using internal reference. The output full-scale current IOUT is
calculated as Full scale output voltage (typ. 1.28V) /220Ω=typ. 5.82mA.
Note 2) DAC output when feeding code of 0 (Decimal).
Note 3) Deviation between the DAC output when feeding 1V generating code of 800(Decimal).
Note 4) The value is a design target. This value is not tested.
