TDA9910
12-bit, up to 80 Msample/s, Analog-to-Digital Converter (ADC)
where:
The value of k is usually 6 (i.e. calculation of THD is done on the first 5 harmonics).
10.2.4
SNR (signal-to-noise ratio)
The ratio of the output signal power to the noise power, excluding the harmonics and the
DC component is:
10.2.5
SFDR (spurious free dynamic range)
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:
