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 bandwidth 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, AES17-199, and
the Electronic Industries Association of Japan, EIAJ CP-307. Expressed in decibels. The dynamic range is
specified with and without an A-weighting filter.
The ratio of the rms value of the signal to the rms sum of all other spectral components over the specified
bandwidth (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. Specified using an A-weighting filter.
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 one channel and all remaining channels, measured for each channel at the
converter's output with no signal to the input under test and a full-scale signal applied to all other channels.
Units in decibels.
The gain difference between left and right channels. 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.
The deviation from linear phase within a given channel.
The difference in phase response between channels.
