Signal-to-Noise-and-Distortion (SINAD)
The ratio of the rms signal amplitude (set 1 dB below full scale)
to the rms value of the sum of all other spectral components,
including harmonics, but excluding dc and image spur.
Signal-to-Noise Ratio (SNR)
The ratio of the rms signal amplitude (set at 1 dB below full
scale) to the rms value of the sum of all other spectral compo-
nents, excluding the first five harmonics and dc.
Spurious-Free Dynamic Range (SFDR)
The ratio of the rms signal amplitude to the rms value of the
peak spurious spectral component, except the image spur. The
peak spurious component may or may not be a harmonic. It can
be reported in dBc (that is, degrades as signal level is lowered)
or dBFS (always related back to converter full-scale).

Total Noise
Calculated as
where:
Z is the input impedance.
FS is the full scale of the device for the frequency in question.
SNR is the value of the particular input level.
Signal is the signal level within the ADC reported in dB below
full scale. This value includes both thermal and quantization noise.
Two-Tone Intermodulation Distortion Rejection
The ratio of the rms value of either input tone to the rms value
of the worst third-order intermodulation product; reported in dBc.
Two-Tone SFDR
The ratio of the rms value of either input tone to the rms value
of the peak spurious component. The peak spurious component
may or may not be an IMD product. It can be reported in dBc
(that is, degrades as signal level is lowered) or in dBFS (always
related back to converter full-scale).
