APPLICATIONS
Printed Circuit Layout
For optimum filter performance, an LTC1164-8 should be
operating on a printed circuit board that has been laid out
for precision analog signal processing circuits. On a
printed circuit board, an LTC1164-8 should be surrounded
with an adequate analog signal ground plane and its power
supply pins bypassed to ground with 0.1μF capacitors.
The ground plane of an LTC1164-8 and any digital ground
plane should preferably meet at a single point on a system
ground (star system ground).
The following external filter connections should be one
inch or less:

Any signal or power supply printed circuit traces should
be at least 0.2 inches away from the above mentioned
connections (this rule applies also to the routing of the
printed circuit trace originating from a clock source in a
digital circuit and terminating at a clock input pin of an
LTC1164-8). Operating an LTC1164-8 in an IC socket is
not recommended.
