DEFINITIONS
Dynamic Range
The ratio of a full-scale output signal to the integrated output
noise in the passband (20 Hz to 20 kHz), expressed in decibels
(dB). Dynamic range is measured with a –60 dB input signal
and is equal to (S/[THD+N]) 60 dB. Note that spurious har-
monics are below the noise with a –60 dB input, so the noise
level establishes the dynamic range. The dynamic range is speci-
fied with and without an A-Weight filter applied.
Signal to (Total Harmonic Distortion + Noise)
(S/(THD + N))
The ratio of the root-mean-square (rms) value of the fundamen-
tal input signal to the rms sum of all other spectral components
in the passband, expressed in decibels (dB).
Signal to Total Harmonic Distortion (S/THD)
The ratio of the rms value of the fundamental input signal to the
rms sum of all harmonically related spectral components in the
passband, expressed in decibels.
Passband
The region of the frequency spectrum unaffected by the attenu-
ation of the digital decimator’s filter.
Passband Ripple
The peak-to-peak variation in amplitude response from equal-
amplitude input signal frequencies within the passband,
expressed in decibels.
Stopband
The region of the frequency spectrum attenuated by the digital
decimator’s filter to the degree specified by “stopband
attenuation.”
Gain Error
With a near full-scale input, the ratio of actual output to
expected output, expressed as a percentage.
Interchannel Gain Mismatch
With identical near full-scale inputs, the ratio of outputs of the
two stereo channels, expressed in decibels.
Gain Drift
Change in response to a near full-scale input with a change in
temperature, expressed as parts-per-million (ppm) per
°C.
Midscale Offset Error
Output response to a midscale dc input, expressed in least-
significant bits (LSBs).
Midscale Drift
Change in midscale offset error with a change in temperature,
expressed as parts-per-million (ppm) per
°C.
Crosstalk (EIAJ Method)
Ratio of response on one channel with a grounded input to a
full-scale 1 kHz sine-wave input on the other channel, expressed
in decibels.
Power Supply Rejection
With no analog input, signal present at the output when a
300 mV p-p signal is applied to power supply pins, expressed in
decibels of full scale.
Group Delay
Intuitively, the time interval required for an input pulse to
appear at the converter’s output, expressed in milliseconds
(ms). More precisely, the derivative of radian phase with respect
to radian frequency at a given frequency.
Group Delay Variation
The difference in group delays at different input frequencies.
Specified as the difference between largest and the smallest
group delays in the passband, expressed in microseconds (
µs).
