The Enable and Control pins should be at VCC or GND
logic levels, VCC being recognized as logic high and GND
being recognized as a logic low. Unused analog
inputs/outputs may be left floating (not connected).
However, it is advisable to tie unused analog inputs and
outputs to VCC or VEE through a low value resistor. This
minimizes crosstalk and feedthrough noise that may be
picked up by the unused I/O pins.
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 the example
below, the difference between VCC and VEE is 12 V.
Therefore, using the configuration in Figure 17, a maximum
analog signal of twelve volts peak−to−peak can be
controlled.
When voltage transients above VCC and/or below VEE are
anticipated on the analog channels, external diodes (Dx) are
recommended as shown in Figure 18. These diodes should
be small signal, fast turn−on types able to absorb the
maximum anticipated current surges during clipping. An
alternate method would be to replace the Dx diodes with
MOSORBs (MOSORBt is an acronym for high current
surge protectors). MOSORBs are fast turn−on devices
ideally suited for precise dc protection with no inherent wear
out mechanism.
