Figure 6-2. Differential Input

Figure 6-2 shows the differential mode (multiplexer not shown).

A single-ended input has no common mode range because there is only one LOW wire, the level of which is assumed to

be the same, signal source and A/D board (Figure 6-3).

The maximum difference which can be rejected is the CMR.

For example, the CIO-DAS16/330 has a common mode plus signal range of 11.5 volts, common mode not to exceed 10

volts.
