TERMINOLOGY
Integral Nonlinearity (INL)
This is the maximum deviation of any code from a straight line
passing through the endpoints of the transfer function. The
endpoints of the transfer function are zero scale and full scale.
The error is expressed in LSBs.
Differential Nonlinearity (DNL)
This is the difference between the measured and ideal 1 LSB
change between two adjacent codes in the DAC. A specified
differential nonlinearity of ±1 LSB maximum ensures
monotonicity.
Output Compliance
The output compliance refers to the maximum voltage that can
be generated at the output of the DAC to meet the specifica-
tions. When voltages greater than that specified for the output
compliance are generated, the AD5930 may not meet the
specifications listed in the data sheet.
Spurious-Free Dynamic Range (SFDR)
Along with the frequency of interest, harmonics of the
fundamental frequency and images of these frequencies are
present at the output of a DDS device. The SFDR refers to the
largest spur or harmonic that is present in the band of interest.
The wide band SFDR gives the magnitude of the largest
harmonic or spur relative to the magnitude of the fundamental
frequency in the 0 to Nyquist bandwidth. The narrow band
SFDR gives the attenuation of the largest spur or harmonic in a
bandwidth of ±200 kHz about the fundamental frequency.

Total Harmonic Distortion (THD)
THD is the ratio of the rms sum of harmonics to the rms value
of the fundamental. For the AD5930, THD is defined as
where:

through the sixth harmonic.
Signal-to-Noise Ratio (SNR)
SNR is the ratio of the rms value of the measured output signal
to the rms sum of all other spectral components below the
Nyquist frequency. The value for SNR is expressed in decibels.
Clock Feedthrough
There is feedthrough from the MCLK input to the analog
output. Clock feedthrough refers to the magnitude of the
MCLK signal relative to the fundamental frequency in the
AD5930’s output spectrum.
