DYNAMIC PERFORMANCE
Signal-to-Noise Plus Distortion Ratio
The signal-to-noise plus distortion ratio [S/(N+D)] is the
ratio between the RMS amplitude of the fundamental input
frequency and the RMS amplitude of all other frequency
components at the ADC output. The output is band lim-
ited to frequencies above DC to below half the sampling
frequency.
Signal-to-Noise Ratio
The signal-to-noise (SNR) is the ratio between the RMS
amplitudeofthefundamentalinputfrequencyandtheRMS
amplitude of all other frequency components, except the
rst ve harmonics.
Total Harmonic Distortion
Total harmonic distortion is the ratio of the RMS sum
of all harmonics of the input signal to the fundamental
itself. The out-of-band harmonics alias into the frequency
band between DC and half the sampling frequency. THD
is expressed as:
THD = –20Log
(√(V22 + V32 + V42 + ... VN2)/V1)
where V1 is the RMS amplitude of the fundamental fre-
quencyandV2throughVNaretheamplitudesofthesecond
through nth harmonics.
Intermodulation Distortion
If the ADC input signal consists of more than one spectral
component, the ADC transfer function nonlinearity can
produce intermodulation distortion (IMD) in addition to
THD. IMD is the change in one sinusoidal input caused
by the presence of another sinusoidal input at a different
frequency.
If two pure sine waves of frequencies fa and fb are applied
totheADCinput,nonlinearitiesintheADCtransferfunction
can create distortion products at the sum and difference
frequencies of mfa ± nfb, where m and n = 0, 1, 2, 3, etc.
For example, the 3nd order IMD terms include (2fa + fb),
(fa + 2fb), (2fa - fb) and (fa - 2fb). The 3rd order IMD is
dened as the ration of the RMS value of either input tone
to the RMS value of the largest 3rd order IMD product.
Spurious Free Dynamic Range (SFDR)
The ratio of the RMS input signal amplitude to the RMS
value of the peak spurious spectral component expressed
in dBc. SFDR may also be calculated relative to full scale
and expressed in dBFS.
Full Power Bandwidth
The Full Power bandwidth is that input frequency at which
theamplitudeofthereconstructedfundamentalisreduced
by 3dB for a full scale input signal.
Aperture Delay Time
The time from when CLK reaches mid-supply to the
instant that the input signal is held by the sample-and-
hold circuit.
Aperture Delay Jitter
The variation in the aperture delay time from convertion
to conversion. This random variation will result in noise
when sampling an AC input. The signal to noise ratio due
to the jitter alone will be:
SNRJITTER = –20log (2
