ELECTRICAL CHARACTERISTICS
VDD = 5V, VREF = 10V, VIOUT = GND = 0V, TA = TMIN to TMAX, unless otherwise specified.
Note 7: To 0.01% for a full-scale change, measured from
falling edge of LD.
Note 8: VREF = 0V. DAC register contents changed from all 0s to all 1s or
from all 1s to all 0s.
Note 9: VREF = 6VRMS at 1kHz. DAC register loaded with all 1s.
Note 10: 10Hz to 100kHz between RFB and IOUT. Calculation from en =
√4KTRB where: K = Boltzmann constant (J/K°); R = resistance ();
T = resistor temperature (
°K); B = bandwidth (Hz).

W
The q denotes specifications which apply over the full operating
temperature range.
Note 1:
±0.5LSB = ±0.012% of full scale.
Note 2: Using internal feedback resistor.
Note 3: Guaranteed by design, not subject to test.
Note 4: IOUT with DAC register loaded with all 0s.
Note 5: Typical temperature coefficient is 100ppm/
°C.
Note 6: IOUT load = 100 in parallel with 13pF.
