PARAMETER DEFINITIONS
Resolution - The total number of possible output codes is equal to 2N, where N = the number of bits
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.
