6. PARAMETER DEFINITIONS
Total Harmonic Distortion + Noise (THD+N)
Dynamic Range
Interchannel Isolation
Interchannel Gain Mismatch
Gain Error
Gain Drift
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.
The ratio of the full scale 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 measurement over the specified bandwidth
made with a -60 dBFS signal. 60 dB is then added to the resulting measurement to refer the measure-
ment to full scale. This technique ensures that the distortion components are below the noise level and
do not effect the measurement. This measurement technique has been accepted by the Audio Engineer-
ing Society, AES17-1991, and the Electronic Industries Association of Japan, EIAJ CP-307.
A measure of crosstalk between the left and right channels. Measured for each channel at the converter's
output with all zeros 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 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.
