The q denotes specifications which apply over the full operating
temperature range.
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: ±1LSB = ±0.0015% of full scale = ±15.3ppm of full scale.
Note 3: Using internal feedback resistor.
Note 4: Guaranteed by design, not subject to test.
Note 5: IOUT1 with DAC register loaded with all 0s.
Note 6: Typical temperature coefficient is 100ppm/C.
Note 7: OUT1 load = 100Ω in parallel with 13pF.
Note 8: To 0.0015% for a full-scale change, measured from the falling
edge of LD1, LD2 or LD.
Note 9: VREF = 6VRMS at 1kHz. DAC register loaded with all 1s;
op amp = LT1007.
Note 10: Calculation from en = √4kTRB where: k = Boltzmann constant
(J/°K); R = resistance (Ω); T = temperature (°K); B = bandwidth (Hz).
Note 11: Minimum high time for STB1, STB2, STB4. Minimum low time
for STB3.
Note 12: Minimum low time for STB1, STB2, STB4. Minimum high time
for STB3.
