Analog Input
Each analog input has four open positions for signal conditioning components. All signal conditioning
components are designated as resistors, but capacitors can be inserted for the construction of R-C filters.
The board is shipped with wire jumpers in one position for each input. The equivalent circuit of one
input is shown in Figure 3-3. For specific applications illustrating signal conditioning with single-ended
inputs, refer to
Application Notes
later in this chapter.
