(Note 9)
Note 1:
Accuracy is guaranteed in the following way:
Note 2:
Offset is measured at the code closest to 10mV.
Note 3:
Gain from V
REF
_ to V
OUT
_ is typically 1.638 x CODE/4096.
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
V
OUT
for DAC A. Repeat the same measurement with DAC A and DAC B interchanged.
DC crosstalk is the maximum
V
OUT
measured.
Note 5:
The DAC output voltage is derived by gaining up V
REF
by 1.638 x CODE/4096. This gain factor may cause V
OUT
to try to
exceed the supplies. The maximum value of V
REF
in the reference input range spec prevents this from happening at full
scale. The minimum V
REF
value of 0.25V is determined by linearity constraints, not DAC functionality.
Note 6:
Accuracy is better than 1LSB for V
OUT
= 10mV to V
DD
- 180mV.
Note 7:
Guaranteed by design. Not production tested.
Note 8:
R

=
∞
and digital inputs are at either V
DD
or GND. V
OUT
= full-scale output voltage.
Note 9:
This timing requirement applies only to
CS
rising edges, which execute commands modifying the DAC input register contents.
