Note 1:
Absolute maximum ratings are those values beyond which the life
of a device may be impaired.
Note 2:
DC offset is measured with respect to Pin 3.
Note 3:
If the internal oscillator is used as the clock source and the divide-
by-4 or divide-by-16 mode is enabled, the supply current is reduced as
much as 40% relative to the divide-by-1 mode.
Note 4:
The maximum clock frequency is arbitrarily defined as the
frequency at which the filter AC response exhibits >1dB of gain peaking.
Note 5:
The minimum clock frequency is arbitrarily defined as the frequecy
at which the filter DC offset changes by more than 5mV.
Note 6:
For more details refer to the Input and Output Voltage Range
paragraph in the Applications Information section.
