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

; f
C
= cutoff frequency.
Figure 1 curve shows the typical phase response of an LTC1064-7
operating at f
CLK
= 1MHz, ratio = 50:1, f
C
= 20kHz and it closely matches
an ideal straight line. The phase shift is described by: phase shift =
180° –
F
(f/f
C
); f ≤ f
C
.
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%.
Note 5: The AC swing is typically 11V

, with ±7.5V, ±5V,
±2.5V Supply respectively. For more information refer to the THD + Noise
