Signal-to-Noise-and-Distortion (SINAD)
The ratio of the rms signal amplitude (set 0.5 dB below full
scale) to the rms value of the sum of all other spectral
components, including harmonics, but excluding dc.
Signal-to-Noise Ratio (Without Harmonics)
The ratio of the rms signal amplitude (set at 0.5 dB below full
scale) to the rms value of the sum of all other spectral
components, 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. The peak spurious
component may or may not be a harmonic. It may be reported
in dBc (that is, degrades as signal level is lowered) or dBFS
(always related back to converter full scale).
Transient Resp onse Time
Transient response time is defined as the time it takes for the
ADC to reacquire the analog input after a transient from 10%
above negative full scale to 10% below positive full scale.
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. May be reported in dBc
(that is, degrades as signal level is lowered) or in dBFS (always
related back to converter full scale).
Worst Other Spur
The ratio of the rms signal amplitude to the rms value of the
worst spurious component (excluding the second and third
harmonic) reported in dBc.
