LTC1064-7
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 LTC1064-7
operating at f
an ideal straight line. The phase shift is described by: phase shift =
180° – F (f/f
F is arbitrarily called the “phase factor” expressed in degrees. The phase
factor allows the calculation of the phase at a given frequency.
Example: The phase shift at 14kHz of the LTC1064-7 shown in Figure 1 is:
phase shift = 180° – 430° (14kHz/20kHz) ± nonlinearity = –121° ± 1% or
–121° ± 1.20°.

Note 3: Group delay and group delay deviation are calculated from the
measured phase factor and phase deviation specifications.
Note 4: Phase deviation and group delay deviation for LTC1064-7MJ is
±4%.
