DEFINITIONS  
Dynamic Range  
With no analog input, signal present at the output when a  
300 mV p-p signal is applied to power supply pins, expressed in  
decibels of full scale.  
The ratio of a full-scale output signal to the integrated output  
noise in the passband (20 Hz to 20 kHz), expressed in decibels  
(dB). Dynamic range is measured with a –60 dB input signal  
and is equal to (S/[THD+N]) 60 dB. Note that spurious har-  
monics are below the noise with a –60 dB input, so the noise  
level establishes the dynamic range. The dynamic range is speci-  
fied with and without an A-Weight filter applied.  
Group Delay  
Intuitively, the time interval required for an input pulse to  
appear at the converter’s output, expressed in milliseconds  
(ms). More precisely, the derivative of radian phase with respect  
to radian frequency at a given frequency.  
Group Delay Variation  
Signal to (Total Harmonic Distortion + Noise)  
(S/(THD + N))  
The ratio of the root-mean-square (rms) value of the fundamen-  
tal input signal to the rms sum of all other spectral components  
in the passband, expressed in decibels (dB).  
The difference in group delays at different input frequencies.  
Specified as the difference between largest and the smallest  
group delays in the passband, expressed in microseconds (µs).
