The limit to the number of expanded inputs is set by the
acceptable error budget of the system.
16-to-1 MUX Response Using Disable vs Shutdown
For a 64-to-1 MUX we need sixteen LT1204s. The
equivalent load resistance due to the feedback resistor
R
EQ
in Disable is 25k/15 = 1.67k. See Figure 3.

= 0.489V
This voltage represents a 2.1% loading error. If the
shutdown feature is used instead of the disable feature,
then the LT1204 could expand to only an 8-to-1 MUX for
the same error.
As a practical matter the gain error at frequency is also
set by capacitive loading. The disabled output capaci-
tance of the LT1204 is about 8pF, and in the case of
sixteen LT1204s, it would represent a 128pF load. The
combination of 1.67k and 128pF correspond to about a
0.3dB roll-off at 5MHz.
