INTERCONNECTION AND SHIELDING
TECHNIQUES
To preserve the high CMR characteristics of
the DASllSSIDASllS6, care must be taken
to minimize noise wherever possible. For best
performance use twisted shielded cable, for
the sensitive input signal, to reduce inductive
and capacitive pickup. The cable should be
connected as close as possible to the input
common mode signal source. Place the gain
setting resistor as close as possible to its re-
spective terminal connections to avoid pick-
up.
