SPURIOUS FREE DYNAMIC RANGE (SFDR) is the difference, expressed in dB, between the desired signal
amplitude to the amplitude of the peak spurious spectral component below one-half the sampling frequency,
where a spurious spectral component is any signal present in the output spectrum that is not present at the input
and may or may not be a harmonic.
TOTAL HARMONIC DISTORTION (THD) is the ratio of the rms total of the first five harmonic components at the
output to the rms level of the input signal frequency as seen at the output, expressed in dB. THD is calculated as
where
• A
f1
is the RMS power of the input frequency at the output and A
f2
through A
f6
are the RMS power in the first 5
harmonic frequencies.
THROUGHPUT TIME is the minimum time required between the start of two successive conversion.
