DEFINITIONS
Dynamic Range
The ratio of a full-scale input signal to the integrated input noise
in the pass band (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 harmonics
are below the noise with a –60 dB input, so the noise level
establishes the dynamic range. The dynamic range is specified
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 pass band, expressed in decibels (dB).
Pass Band
The region of the frequency spectrum unaffected by the attenu-
ation of the digital decimator’s filter.
Pass-Band Ripple
The peak-to-peak variation in amplitude response from equal-
amplitude input signal frequencies within the pass band, expressed
in decibels.
Stop Band
The region of the frequency spectrum attenuated by the digital
decimator’s filter to the degree specified by stop-band 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.
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 microseconds.
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 the largest and the smallest
group delays in the pass band, expressed in microseconds.
