10.PARAMETER DEFINITIONS  
Total Harmonic Distortion + Noise (THD+N)  
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.  
Dynamic Range  
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 measurement 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 Engineering Society, AES17-  
1991, and the Electronic Industries Association of Japan, EIAJ CP-307.  
Interchannel Isolation  
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 deci-  
bels.  
Interchannel Gain Mismatch  
The gain difference between left and right channels. Units in decibels.  
Gain Drift  
The change in gain value with temperature. Units in ppm/°C.  
Intra-Channel Phase Deviation  
The deviation from linear phase within a given channel.  
Inter-Channel Phase Deviation  
The difference in phase between channels.
