PARAMETER DEFINITIONS
Total Harmonic Distortion + Noise (THD+N)- The ratio of the rms value of the signal to the rms
Dynamic Range - The ratio of the full scale rms value of the signal to the rms sum of all other
Interchannel Isolation - A measure of crosstalk between the left and right channels. Measured for
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.

sum of all other spectral components over the specified bandwidth (typically 10 Hz to 20 kHz),
including distortion components. Expressed in decibels.
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.
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.
