PARAMETER DEFINITIONS
Total Harmonic Distortion - The ratio of the rms sum of all harmonics up to 20 kHz to the rms
value of the signal. Units in percent.
Signal-to-Noise plus Distortion Ratio - The ratio of the rms value of the signal to the rms sum of all
other spectral components below the Nyquist rate (excepting dc), including distortion components. Ex-
pressed in decibels.
Dynamic Range - Full-scale Signal-to-Noise plus Distortion with the input signal 60dB below full-
scale. Units in decibels.
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 grounded and a full-scale signal ap-
plied to the other channel. Units in decibels.
Full Scale Error - The deviation of the last code transition from the ideal (VREF-3/2 LSB’s) after all
offsets have been externally compensated. Units in decibels relative to full scale.
Bipolar Offset - The deviation of the mid-scale transition (011...111 to 100...000) from the ideal
(1/2 LSB below AGND). Units in microvolts.
Interchannel Mismatch - The difference in output codes between the left and right channels with the
same analog input applied. Units expressed in decibels relative to full scale. Tested at full scale input.
Aperture Time - The time required after the hold command for the sampling switch to open fully.
Effectively a sampling delay which can be nulled by advancing the sampling signal. Units in nanosec-
onds.
Aperture Jitter - The range of variation in the aperture time. Effectively the "sampling window"
which ultimately dictates the maximum input signal slew rate acceptable for a given accuracy. Units in
picoseconds.
