Note 1: Absolute maximum ratings are those values beyond which the life
of a device may be impaired.
Note 2: Linearity and monotonicity are defined from code k
2
rounded to the nearest whole code. For V
256 and linearity is defined from code 256 to code 65,535.
Note 3: Digital inputs at 0V or V
Note 4: DC crosstalk is measured with V
the measured DAC at midscale, unless otherwise noted.
