ELECTRICAL CHARACTERISTICS (continued)
(AVDD = DVDD = 2.7V to 5.25V, external reference VREF = 2.5V, fCLK = 3.6MHz (50% duty cycle), TA = -40°C to +85°C, unless
otherwise noted. Typical values are at AVDD = DVDD = 3V, TA = +25°C. Outputs are unloaded, unless otherwise noted.)

Note 1: Tested at DVDD = AVDD = 2.7V.
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 4: See Table 5 for reference-mode details.
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 1nF 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 100pF 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 15: All digital inputs at either DVDD or DGND. DVDD should not exceed AVDD.
Note 16: See the
Reset Register section and Table 9 for details on programming the SLOW bit.
Note 17: Clock mode 11 only.
