Note 1: Absolute Maximum Ratings are those values beyond which the life of a
device may be impaired.
Note 2: Input frequencies, f, are linearly phase shifted through the filter as long as
f ≤ f
Figure 1 curve shows the typical phase response of an LTC1164-7 operating at
f
shift is described by: phase shift = 180° – F (f/f
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 3: Group delay and group delay deviation are calculated from the measured
phase factor and phase deviation specifications.
Note 4: The AC swing is typically 11V
supply respectively. For more information refer to the THD + Noise vs Input graphs.
