Figure 1 curve shows the typical phase response of an LTC1164-7 operating at  
= 400kHz, f = 8kHz and it closely matches an ideal straight line. The phase

F is arbitrarily called the “phase factor” expressed in degrees. The phase factor  
together with the specified deviation from the ideal straight line allows the  
calculation of the phase at a given frequency. Example: The phase shift at 7kHz of  
the LTC1164-7 shown in Figure 1 is: phase shift = 180° – 434° (7kHz/10kHz) ±  
nonlinearity = –123.8° ± 1% or –123.9° ± 1.24°.  
Note 2: Group delay and group delay deviation are calculated from the measured  
phase factor and phase deviation specifications.
