APPLICATIONS INFORMATION
The Channel Select and Enable control pins should be at
VCC or GND logic levels. VCC being recognized as a logic
high and GND being recognized as a logic low. In this
example:
VCC = )5 V = logic high
GND = 0 V = logic low
The maximum analog voltage swing is determined by the
supply voltages VCC and VEE. The positive peak analog
voltage should not exceed VCC. Similarly, the negative peak
analog voltage should not go below VEE. In this example,
the difference between VCC and VEE is 5.0 volts. Therefore,
using the configuration of Figure 21, a maximum analog
signal of 5.0 volts peaktopeak can be controlled. Unused
analog inputs/outputs may be left floating (i.e., not
connected). However, tying unused analog inputs and
outputs to VCC 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:
VEE GND = 0 to *6 volts
VCC GND = 2.5 to 6 volts
VCC VEE = 2.5 to 6 volts
and VEE v GND
When voltage transients above VCC and/or below VEE are
anticipated on the analog channels, external Germanium or
Schottky diodes (Dx) are recommended as shown in
Figure 22. These diodes should be able to absorb the
maximum anticipated current surges during clipping.
