ELECTRICAL CHARACTERISTICS (CONTINUED)
Electrical Specifications: Unless otherwise indicated, VDD = 2.7V to 5.5V, VSS = 0V, RL = 5 kΩ from VOUT to GND, CL = 100 pF, TA
= -40°C to +125°C. Typical values at +25°C.

Conditions
Note
1:
This parameter is ensured by design and is not 100% tested.
2:
This gain error does not include offset error. See Section 2 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 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.
7:
VDD = 5.5V.
