This parameter is ensured by design and is not 100% tested.
This gain error does not include offset error. See Section 2 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).
The power-up ramp rate affects on uploading the EEPROM contents to the DAC register. It measures the rise of V_DD
over time.
This parameter is ensured by characterization, and not 100% tested.
The PD1:PD0 = ‘10’, and ‘11’ configurations should have the same current.
V_DD = 5.5V.
