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.
3: 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 V
DD
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.
7: V
