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 exam-
ple:
VCC = +5V = logic high
GND = 0V = logic low
The maximum analog voltage swings are 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 ten volts. Therefore,
using the configuration of Figure 15, a maximum analog sig-
nal of ten volts peak–to–peak can be controlled. Unused
analog inputs/outputs may be left floating (i.e., not con-
nected). 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 require-
ment. The only constraints on the power supplies are that:
VCC – GND = 2 to 6 volts
VEE – GND = 0 to –6 volts
VCC – VEE = 2 to 12 volts
and VEE ≤ 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
16. These diodes should be able to absorb the maximum
anticipated current surges during clipping.
