TERMINOLOGY
Integral Nonlinearity (INL)
The maximum deviation of the actual analog output from the
ideal output, as determined by a straight line drawn from zero
scale to full scale.
Differential Nonlinearity (DNL)
A measure of the maximum deviation in analog output associated
with any single value change in the digital input code relative to
an ideal LSB.
Offset Error
The deviation of the output current from the ideal zero-scale
current. For differential outputs, 0 mA is expected at I
all inputs are low, and 0 mA is expected at I
are high.
Monotonicity
A DAC is monotonic if the analog output increases or remains
constant in response to an increase in the digital input.
Gain Error
The deviation of the output current from the ideal full-scale
current. Actual full-scale output current is determined by
subtracting the output when all inputs are low from the output
when all inputs are high.
Output Compliance Range
The range of allowable voltage seen by the analog output of a
current output DAC. Operation beyond the compliance limits
may cause output stage saturation and/or breakdown resulting
in nonlinear performance.

Temperature Drift
Temperature drift is specified as the maximum change in a
parameter from ambient temperature (25°C) to either T
or T
Power Supply Rejection
The maximum change in the full-scale output as all power
supplies are varied over their respective operating voltage range.
Spurious-Free Dynamic Range (SFDR)
The difference in decibels between the peak amplitude of a test
tone and the peak amplitude of the largest spurious signal over
the specified bandwidth.
Intermodulation Distortion (IMD)
The difference in decibels between the maximum peak
amplitude of two test tones and the maximum peak amplitude
of the distortion products created from the sum or difference
of integer multiples of the test tones.
Adjacent Channel Leakage Ratio (ACLR)
The ratio between the measured power of a wideband signal
within a channel relative to the measured power in an empty
adjacent channel.
Noise Spectral Density (NSD)
The measured noise power over a 1 Hz bandwidth seen at the
analog output.
Total Harmonic Distortion (THD)
The ratio in decibels of the rms power sum of the first six
harmonic components to the rms power of the output signal.
MAX
and is typically reported as ppm/°C.
