Differential Phase,
Φ
, is the phase error from and ideal
sine wave.
Signal to Noise Ratio, SNR,
is the ratio of a fundamental to
the noise floor of the analog output. The first 5 harmonics
are ignored, and an output filter of
1
/
2
the clock frequency is
used to eliminate alias products.
Total Harmonic Distortion, THD
, is the ratio of the DAC
output fundamental to the RMS sum of the harmonics. The
first 5 harmonics are included, and an output filter of
1
/
2
the
clock frequency is used to eliminate alias products.
Spurious Free Dynamic Range, SFDR
, is the amplitude
difference from a fundamental to the largest harmonically or
non-harmonically related spur. A sine wave is loaded into the
D/A and the output filtered at
1
/
2
the clock frequency to
eliminate noise from clocking alias terms.
Intermodulation Distortion, IMD
is the measure of the sum
and difference products produced when a two tone input is
driven into the D/A. The distortion products created will arise
at sum and difference frequencies of the two tones. IMD is
