SPURIOUS FREE DYNAMIC RANGE (SFDR) is the difference, expressed in dB, between the rms values of the
input signal at the output and the peak spurious signal, where a spurious signal is any signal present in the
output spectrum that is not present at the input.
TOTAL HARMONIC DISTORTION (THD) is the ratio, expressed in dB, of the total of the first nine harmonic
levels at the output to the level of the fundamental at the output. THD is calculated as
where
• where F
1
is the RMS power of the fundamental (input) frequency and f
2
through f
10
is the power in the first 9
harmonics in the output spectrum. (2)
ZERO SCALE OFFSET ERROR is the error in the input voltage required to cause the first code transition. It is
defined as
V
OFF
= V
ZT
− V
RB
where
• where V
ZT
is the first code transition input voltage. (3)
