Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: Phase Deviation = 1/2(Phase at 0Hz – Phase at f
at 0Hz – Phase at 0.5f
CUTOFF
Phase at 0Hz = 180° (guaranteed by design)
