1V. A linearity error temperature coefficient of 0.0002% FS for a 45
§
C rise only guarantees 0.009% maximum change in
linearity error. For instance, if the linearity error at 25
§
C is 0.045% FS it could increase to 0.054% at 70
§
C and the DAC will be no longer a 10-bit part. Note,
however, that the linearity error is specified over the device full temperature range which is a more stringent specification since it includes the linearity error
temperature coefficient.

Note 5:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not apply when operating
the device beyond its specified operating conditions.
