Signal-to-Noise Ratio (without harmonics)
Temperature Drift
SNR is a measure of signal strength relative to
background noise. The ratio is usually measured in
dB. If the incoming signal strength in μV is V
S
and the
noise level (also in μV) is V
N
, then the SNR in dB is
given by the formula:
Temperature drift (for offset error and gain error)
specifies the maximum change from the initial tem-
perature value to the value at T
MIN
or T
MAX
.
Total Harmonic Distortion (THD)
THD is the ratio of the RMS signal amplitude of the
input sine wave to the RMS value of distortion
appearing at multiples (harmonics) of the input, typi-
cally given in dBc.
This is the ratio of the RMS signal amplitude, V
S
(set
1dB below full-scale), to the RMS value of the sum of
all other spectral components, V
N
, excluding harmon-
ics and DC.
Two-Tone Intermodulation Distortion Rejection
The ratio of the RMS value of either input tone (f
1
, f
2
)
to
the
RMS
value
of
intermodulation product (2f
1
- f
2
; 2f
2
- f
1
). It is reported
in dBc.
the
worst
third-order
Spurious-Free Dynamic Range (SFDR)
The ratio of the RMS value of the analog input sine
wave to the RMS value of the peak spur observed in
the frequency domain. It may be reported in dBc (that
is, it degrades as signal levels are lowered), or in
dBFS (always related back to converter full-scale).
The peak spurious component may or may not be a
harmonic.
