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

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 VDD

over time.

This parameter is ensured by characterization, and not 100% tested.

The PD1:PD0 = ‘10’, and ‘11’ configurations should have the same current.

VDD = 5.5V.
