PARAMETER DEFINITIONS
Resolution
The number of bits in the input words to the DACs, and in the output words in the ADCs.
Differential Nonlinearity
The worst case deviation from the ideal codewidth; expressed in LSBs.
Total Dynamic Range
The ratio between the DAC full scale output and the noise floor with the DAC muted. Units are
in dB.
Total Harmonic Distortion + Noise (THD+N)
THD+N is the ratio of the rms value of the input signal to the rms sum of all other spectral
components within the measurement bandwidth (10Hz to 20kHz). THD+N is expressed in dB.
Total Harmonic Distortion (THD)
THD is the ratio of the test signal amplitude to the rms sum of all the in-band harmonics of the
test signal.
Instantaneous Dynamic Range
The S/(N+D) with a 1kHz, -60dB input signal, with 60dB added to compensate for the small
input signal. Use of a small input signal reduces the harmonic distortion components of the
noise to insignificance. Units are in dB.
Interchannel Isolation
The amount of 1kHz signal present on the output of the grounded input channel with 1kHz,
0dB signal present on the other channel. Units are in dB.
Interchannel Gain Mismatch
For the ADCs, the difference in input voltage that generates the full scale code for each
channel. For the DACs, the difference in output voltages for each channel with a full scale
digital input. Units are in dB.
Frequency Response
Worst case variation in output signal level versus frequency over 10Hz to 20kHz. Units in dB.
Offset Error
For the ADCs, the deviation in LSB’s of the output from mid-scale with the selected input
grounded. For the DAC’s, the deviation of the output from zero with mid-scale input code.
Units are in volts.
