Typical values at +25°C. Parameters Symbol Min Typical Max Units 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. |
