PARAMETER DEFINITIONS
Total Harmonic Distortion + Noise - The ratio of the rms value of the signal to the rms sum of all
Signal-to-Noise Ratio - The ratio of the full scale rms value of the signal to the rms sum of all other
Frequency Response - A measure of the amplitude response variation from 10 Hz to 20 kHz relative
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.
Offset Error - The deviation of the mid-scale transition (111...111 to 000...000) from the ideal
DS62F3
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 with an input of all zeros.
to the amplitude response at 1 kHz. Units in decibels.
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.
(AGND). Units in mV.
