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 specifi ed 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 specifi ed pins is constant for
all output ranges if the I

Note 5: Using LT1469 with C
of 1.7μs can be achieved by optimizing the time constant on an individual
basis. See Application Note 74, Component and Measurement Advances

Note 7. Full-scale transition; REF = 0V.
Note 8. Analog Crosstalk is defi ned as the AC voltage ratio V
expressed in dB. REFB is grounded, and DAC B is set to 0V-5V span and
zero-, mid- or full- scale code. V
between other DAC channels is similar or better.
