GETTING STARTED WITH THE PICKIT SERIAL ANALYZER
FIGURE 1-1:
Figure 1-1 shows the MCP3422 Evaluation Board and Figure 1-2 shows the MCP3422
Evaluation Board and PICkit Serial Analyzer.
The following instructions describe how to use them together:
1. Connect the MCP3422 Evaluation Board’s 6-pin socket to the PICkit Serial
2. Connect the oscilloscope probes to the SCL and SDA test pins (optional).
3. V
4. Connecting V
5. Connecting the analog inputs: If you need to measure a single-ended input,
• Connecting the inputs: The MCP3422 Evaluation Board has input pads for
analog inputs for each input channel. You can connect all inputs at the same time
and multiplex the input channel using configuration register settings. You can also
leave the unused channel inputs floating.
