8. 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 affect 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 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.
