Definition of Specifications
Differential Non-Linearity (DNL)
is the measure of the step
size output deviation from code to code. Ideally the step size
should be one LSB. A DNL specification of one LSB or less
guarantees monotonicity.
Integral Non-Linearity (INL)
is the measure of the worst
case point that deviates from a best fit straight line of data
values along the transfer curve.
Full Scale Gain Drift
is measured by setting the DAC inputs
to be all logic high (all 1’s) and measuring the output voltage
through a known resistance as the temperature is varied
from T
MIN
to T
MAX
. It is defined as the maximum
deviation

NOTES:
2. Gain error for the DAC is measured as the error in the ratio between the full scale output current and the current through R
SET
(typically 625
μ
A);
ideally the ratio should be 32.
3. Parameter guaranteed by design or characterization and not production tested.
4. Spectral measurements made with differential transformer coupled output and no external filtering.
5. Measured with the clock at 125MSPS and the output frequency at 10MHz.
6. Measured with the clock at 100MSPS and the output frequency at 10MHz.
