PARAMETER DEFINITIONS

Resolution - The total number of possible output codes is equal to 2

in the output word for each channel.

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.

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 band width (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.

Total Harmonic Distortion - The ratio of the rms sum of all harmonics up to 20 kHz to the rms value

of the signal.

Interchannel Phase Deviation - The phase difference between the left and right channel sampling

times.

Interchannel Isolation - A measure of crosstalk between the left and right channels. Measured for

each channel at the converter’s output with the input under test AC grounded 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 of the measured full scale amplitude from the ideal full scale amplitude

value.

Gain Drift - The change in gain value with temperature. Units in ppm/

°C.

Bipolar Offset Error - The deviation of the mid-scale transition (111...111 to 000...000) from the

ideal. Units in LSBs.
