Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: Continuous operation above the specied maximum operating
junction temperature may impair device reliability.
Note 3: Because of the proprietary SoftSpan switching architecture, the
measured resistance looking into each of the specied pins is constant for
all output ranges if the IOUT1X and IOUT2X pins are held at ground.
Note 4: R1 is measured from RIN to RCOM; R2 is measured from REFA to
RCOM.
Note 5: Using LT1469 with CFEEDBACK = 15pF. A ±0.0015% settling time
of 1.7μs can be achieved by optimizing the time constant on an individual
basis. See Application Note 74, Component and Measurement Advances
Ensure 16-Bit DAC Settling Time.
Note 6: Measured at the major carry transition, 0V to 5V range. Output
amplier: LT1469; CFB = 27pF.
Note 7. Full-scale transition; REF = 0V.
Note 8. REF = 6VRMS at 1kHz. 0V to 5V range. DAC code = FS. Output
amplier = LT1469.
Note 9. Calculation from Vn = √4kTRB, where k = 1.38E-23 J/°K
(Boltzmann constant), R = resistance (Ω), T = temperature (°K), and B =
bandwidth (Hz).
Note 10. Guaranteed by design. Not production tested.
TIMING CHARACTERISTICS The denotes specications that apply over the full operating temperature range,
otherwise specications are at TA = 25°C.
