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
VOUT over the temperature range is
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
VOUT for DAC A. Repeat the same measurement with DAC A and DAC B interchanged.
DC crosstalk is the maximum
VOUT measured.
Note 5: Accuracy is better than 1LSB for VOUT_ = 12mV to VDD - 180mV.
Note 6: Guaranteed by design, not production tested.
Note 7: RLOAD = ∞ and digital inputs are at either VDD or DGND.
