TERMINOLOGY
Total System Accuracy
The AD5933 can accurately measure a range of impedance
values to less than 0.5% of the correct impedance value for
supply voltages between 2.7 V to 5.5 V.
Spurious-Free Dynamic Range (SFDR)
Along with the frequency of interest, harmonics of the funda-
mental frequency and images of these frequencies are present at
the output of a DDS device. The spurious-free dynamic range
refers to the largest spur or harmonic present in the band of
interest. The wideband SFDR gives the magnitude of the largest
harmonic or spur relative to the magnitude of the fundamental
frequency in the 0 Hz to Nyquist bandwidth. The narrow-band
SFDR gives the attenuation of the largest spur or harmonic in a
bandwidth of ±200 kHz, about the fundamental frequency.
Signal-to-Noise Ratio (SNR)
SNR is the ratio of the rms value of the measured output signal
to the rms sum of all other spectral components below the
Nyquist frequency. The value for SNR is expressed in decibels.
Total Harmonic Distortion (THD)
THD is the ratio of the rms sum of harmonics to the funda-
mental, where V1 is the rms amplitude of the fundamental
and V2, V3, V4, V5, and V6 are the rms amplitudes of the
second through the sixth harmonics. For the AD5933, THD
is defined as
