ADC1206S040/055/070
Single 12 bits ADC, up to 40 MHz, 55 MHz or 70 MHz
13.2.3
Total Harmonic Distortion (THD)
The ratio of the power of the harmonics to the power of the fundamental. For k-1
harmonics the THD is:
where
The value of k is usually 6 (i.e. calculation of THD is done on the first 5 harmonics).
13.2.4
Signal-to-Noise ratio (S/N)
The ratio of the output signal power to the noise power, excluding the harmonics and the
P
P
noise
DC component.
13.2.5
Spurious Free Dynamic Range (SFDR)
The number SFDR specifies available signal range as the spectral distance between the
amplitude of the fundamental and the amplitude of the largest spurious (harmonic and
non-harmonic, excluding DC component).
13.3 Intermodulation distortion
13.3.1
Spectral analysis (dual-tone)
From a dual-tone input sinusoid (f
t
1 and f
t
2, these frequencies being chosen according to
the coherence criterion), the intermodulation distortion products IMD2 and IMD3
(respectively, 2nd and 3rd order components) are defined, as follows.
