Plot, Harmonic Distortion 3.0 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 six volts. Therefore, using the configuration in Figure 16, a maximum analog signal of six 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.
