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: All voltages are with respect to GND.
Note 3: High temperatures degrade operating lifetimes. Operating lifetime
is derated at temperatures greater than 105°C.

Note 6: This IC includes current limiting that is intended to protect the
device during momentary overload conditions. Junction temperature can
exceed the rated maximum during current limiting. Continuous operation
above the specifi ed maximum operating junction temperature may impair
device reliability.
Note 7: Digital inputs at 0V or V
Note 8: Guaranteed by design and not production tested.
Note 9: Internal Reference mode. DAC is stepped 1/4 scale to 3/4 scale
and 3/4 scale to 1/4 scale. Load is 2k in parallel with 100pF to GND.
Note 10: Temperature coeffi cient is calculated by dividing the maximum
change in output voltage by the specifi ed temperature range.
Note 11: Full-scale error is determined using the reference voltage
measured at the REF pin.
