Signal-to-(Noise + Distortion) (SINAD) Ratio
This is the measured ratio of SINAD at the output of the ADC.
The signal is the rms amplitude of the fundamental. Noise is the
sum of all nonfundamental signals up to half the sampling
frequency (fS/2), excluding dc. The ratio is dependent on the
number of quantization levels in the digitization process, the
more levels, the smaller the quantization noise. The theoretical
SINAD ratio for an ideal N-bit converter with a sine wave input
is given by
SINAD = (6.02N + 1.76) dB
Thus for a 12-bit converter, this is 74 dB.
Total Harmonic Distortion (THD)
THD is the ratio of the rms sum of harmonics to the
fundamental. For the AD7923, it is defined as

sixth harmonics.
