V CC or GND logic levels. V CC being recognized as a logic
high and GND being recognized as a logic low. In this exam-
ple:
the supply voltages V CC and V EE . The positive peak analog
voltage should not exceed V CC . Similarly, the negative peak
analog voltage should not go below V EE . In this example, the
difference between V CC and V EE 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

anticipated on the analog channels, external Germanium or
Schottky diodes (D x ) are recommended as shown in Figure
16. These diodes should be able to absorb the maximum
anticipated current surges during clipping.
