The ratio of the rms value of the signal to the rms sum of all other spectral components over the specified
bandwidth. Dynamic Range is a signal-to-noise ratio measurement over the specified band width made with
a -60 dBFS signal. 60 dB is added to resulting measurement to refer the measurement to full-scale. This
technique ensures that the distortion components are below the noise level and do not affect the measure-
ment. This measurement technique has been accepted by the Audio Engineering Society, AES17-1991,
and the Electronic Industries Association of Japan, EIAJ CP-307. Expressed in decibels.
The ratio of the rms value of the signal to the rms sum of all other spectral components over the specified
band width (typically 10 Hz to 20 kHz), including distortion components. Expressed in decibels. Measured
at -1 and -20 dBFS as suggested in AES17-1991 Annex A.
A measure of the amplitude response variation from 10 Hz to 20 kHz relative to the amplitude response at
1 kHz. Units in decibels.
A measure of crosstalk between the left and right channel pairs. Measured for each channel at the convert-
er's output with no signal to the input under test and a full-scale signal applied to the other channel. Units in
decibels.
The gain difference between left and right channel pairs. Units in decibels.
The deviation from the nominal full-scale analog output for a full-scale digital input.
The change in gain value with temperature. Units in ppm/°C.
The deviation of the mid-scale transition (111...111 to 000...000) from the ideal. Units in mV.
