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
OUT1X
and I
OUT2X
pins are held at ground.

between other DAC channels is similar or better.
