Note 1: Accuracy is guaranteed as shown in the following table:

Note 2: Offset is measured at the code closest to 12mV.

Note 3: Temperature coefficient is determined by the box method in which the maximum

divided by

∆T.

Note 4: DC crosstalk is measured as follows: set DAC A to midscale, and DAC B to zero, and measure DAC A output; then change

DAC B to full scale, and measure

DC crosstalk is the maximum

Note 6: Guaranteed by design, not production tested.
