Signal-to-Noise and Distortion (SINAD)
SINAD is computed by taking the ratio of the RMS
signal to the RMS noise plus the RMS distortion. RMS
noise includes all spectral components to the Nyquist
frequency excluding the fundamental, the first six
harmonics (HD2–HD7), and the DC offset. RMS
distortion includes the first six harmonics (HD2–HD7).

Single-Tone Spurious-Free
Dynamic Range (SFDR)
SFDR is the ratio expressed in decibels of the RMS
amplitude of the fundamental (maximum signal
component) to the RMS amplitude of the next largest
spurious component, excluding DC offset.
Total Harmonic Distortion (THD)
THD is the ratio of the RMS of the first six harmon-
ics of the input signal to the fundamental itself. This is
expressed as:

V1 is the fundamental amplitude and V2–V7 are the
amplitudes of the 2nd-order through 7th-order harmon-
ics (HD2–HD7).
Intermodulation Distortion (IMD)
IMD is the ratio of the RMS sum of the intermodulation
products to the RMS sum of the two fundamental input
tones. This is expressed as:

V1 and V2 are amplitudes of the two fundamental inputs,
and VIMn is the amplitude of the nth intermodulation
product. The fundamental input tone amplitudes (V1 and
V2) are at -6.5dBFS. Fourteen intermodulation products
(VIMn) are used in the ADC IMD calculation. The inter-
modulation products are the amplitudes of the output
spectrum at the following frequencies, where fIN1 and
fIN2 are the fundamental input tone frequencies:
U
Second-order intermodulation products:
fIN1 + fIN2, fIN2 - fIN1
U
Third-order intermodulation products:
2 x fIN1 - fIN2, 2 x fIN2 - fIN1,
2 x fIN1 + fIN2, 2 x fIN2 + fIN1
U
Fourth-order intermodulation products:
3 x fIN1 - fIN2, 3 x fIN2 - fIN1,
3 x fIN1 + fIN2, 3 x fIN2 + fIN1
U
Fifth-order intermodulation products:
3 x fIN1 - 2 x fIN2, 3 x fIN2 - 2 x fIN1,
3 x fIN1 + 2 x fIN2, 3 x fIN2 + 2 x fIN1
Overdrive Recovery Time
Overdrive recovery time is the time required for the
ADC to recover from an input transient that exceeds the
full-scale limits. The specified overdrive recovery time
is measured with an input carrier that exceeds the full-
scale limits by 6dBFS.
