ELECTRICAL CHARACTERISTICS (continued)

Note 2: Offset nulled.

Note 3: No bus activity during conversion. Conversion time is defined as the number of conversion clock cycles multiplied by the

clock period.

Note 5: Not production tested. Guaranteed by design.

Note 6: See the ADC/DAC References section.

Note 7: Fast automated test, excludes self-heating effects.

Note 8: Specified over the -40°C to +85°C temperature range.

Note 9: REFSEL[1:0] = 00 or when DACs are not powered up.

Note 10: DAC linearity, gain, and offset measurements are made between codes 115 and 3981.

Note 11: The DAC buffers are guaranteed by design to be stable with a 500pF load.

Note 12: Time required by the DAC output to power up and settle within 1 LSB in the external reference mode.

Note 13: All DAC dynamic specifications are valid for a load of 1nF and 10kΩ.

Note 14: Only one digital output (either DOUT, EOC, or the GPIOs) can be indefinitely shorted to either supply at one time.

Note 17: Clock mode 11 only.
