APPLICATIONS INFORMATION
The Channel Select and Enable control pins should be at
V
CC
or GND logic levels. V
CC
being recognized as a logic
high and GND being recognized as a logic low. In this
example:
V
CC
=
5 V = logic high
GND = 0 V = logic low
The maximum analog voltage swing is determined by the
supply voltages V
CC
and V
EE
. The positive peak analog
voltage should not exceed V
CC
. Similarly, the negative peak
analog voltage should not go below V
EE
. In this example,
the difference between V
CC
and V
EE
is five volts. Therefore,
using the configuration of Figure 21, a maximum analog
signal of five volts peak–to–peak can be controlled. Unused
analog inputs/outputs may be left floating (i.e., not
connected). However, tying unused analog inputs and
outputs to V
CC
or GND through a low value resistor helps
minimize crosstalk and feedthrough noise that may be
picked up by an unused switch.
Although used here, balanced supplies are not a
requirement. The only constraints on the power supplies are
that:
V
EE
– GND = 0 to
V
CC
– GND = 2.5 to 6 volts
V
CC
– V
EE
= 2.5 to 6 volts
and V
EE
When voltage transients above V
CC
and/or below V
EE
are
anticipated on the analog channels, external Germanium or
Schottky diodes (D
x
) are recommended as shown in
Figure 22. These diodes should be able to absorb the
maximum anticipated current surges during clipping.
