APPLICATION INFORMATION
The ON/OFF 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
GND 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 GND. The positive peak analog
voltage should not exceed VCC. Similarly, the negative peak
analog voltage should not go below GND. In the example
below, the difference between VCC and GND is twelve volts.
Therefore, using the configuration in Figure 16, a maximum
analog signal of twelve volts peak−to−peak can be
controlled.
When voltage transients above VCC and/or below GND
are anticipated on the analog channels, external diodes (Dx)
are recommended as shown in Figure 17. 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 (Mosorb™ 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.
