APPLICATIONS INFORMATION 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 21, a maximum analog signal of ten 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 VCC or GND through a low value resistor helps minimize crosstalk and feed−through 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: VCC − GND = 2 to 6 V VEE − GND = 0 to −6 V VCC − VEE = 2 to 12 V 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 22. These diodes should be able to absorb the maximum anticipated current surges during clipping. |
