Note 1:
Absolute Maximum Ratings are those values beyond which
the life of the device may be impaired.
Note 2:
Connecting any input terminal to voltages greater than V
+
or
less than ground may cause destructive latch-up. It is recommended
that no inputs from sources operating from external supplies be
applied prior to power-up of the LTC1046.
Note 3:

C immediately after power-on.
Note 4:
f
OSC
is tested with C
OSC
= 100pF to minimize the effects of test
fixture capacitance loading. The 0pF frequency is correlated to this 100pF
test point, and is intended to simulate the capacitance at pin 7 when the
device is plugged into a test socket and no external capacitor is used.
