Note 1:
This parameter is ensured by design and is not 100% tested.
2:
This Gain error does not include Offset error. See
Section 1.0 “Electrical Characteristics”
for more details in plots.

Within 1/2 LSb of final value when code changes from 1/4 to 3/4 of FSR. (Example: 400h to C00h in 12-bit device).
4:
The power-up ramp rate affects on uploading the EEPROM contents to the DAC register. It measures the rise of VDD over time.
5:
This parameter is ensured by characterization, and not 100% tested.
6:
The PD1:PD0 = 10, and ‘11’ configurations should have the same current.
