Note 9: VREF = 0V. DAC register contents changed from all 0s to all 1s or
all 1s to all 0s. LD high, WR and MLBYTE pulsed.
Note 10: VREF = 6VRMS at 1kHz. DAC register loaded with all 1s.
RL = 600. Unipolar mode op amp = LT1468.
Note 11: Calculation from en = √4kTRB where: k = Boltzmann constant
(J/°K), R = resistance (), T = temperature (°K), B = bandwidth (Hz).
Note 12: Midscale transition code 0111 1111 1111 1111 to
1000 0000 0000 0000.
Note 13: R1 and R2 are measured between R1 and RCOM, R2 and RCOM.
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: I(OUT1) with DAC register loaded to all 0s.
Note 6: Typical temperature coefficient is 100ppm/°C.
Note 7: IOUT1 load = 100 in parallel with 13pF.
Note 8: To 0.0015% for a full-scale change, measured from the falling
edge of LD.
