The following two figures, Figures 4- 2 and 4-3, provide examples of the configuration of analog
current signal outputs.
Figure 4-2 indicates a configuration where the external source voltage (V
ext
) is the same for all
four channels of cluster A. This example demonstrates the use of the common tie point pins for
V
ext
.
