10.PARAMETER DEFINITIONS
Dynamic Range
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 measurement. This measurement technique
has been accepted by the Audio Engineering Society, AES17-1991, and the Electronic Industries Association of Ja-
pan, EIAJ CP-307. Expressed in decibels.
Total Harmonic Distortion + Noise
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.
Frequency Response
A measure of the amplitude response variation from 10 Hz to 20 kHz relative to the amplitude response at 1 kHz.
Units in decibels.
Interchannel Isolation
A measure of crosstalk between the left and right 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 the other channel. Units in decibels.
Interchannel Gain Mismatch
The gain difference between left and right channels. Units in decibels.
Gain Error
The deviation from the nominal full-scale analog output for a full-scale digital input.
Gain Drift
The change in gain value with temperature. Units in ppm/°C.
Offset Error
The deviation of the mid-scale transition (111...111 to 000...000) from the ideal. Units in mV.
