GETTING STARTED WITH PICKIT SERIAL ANALYZER
FIGURE 1-1:
Figure 1-1 shows the MCP3424 Evaluation Board, and Figure 1-2 shows the
MCP3424 and PICkit Serial Analyzer.
The following describes how to use them together:
1. Connect the MCP3424 Evaluation Board’s 6-pin socket to the PICkit Serial Ana-
2. Connect the oscilloscope probes to the SCL and SDA test pins (optional).
3. V
4. Address bit selection using JP2 and JP3 connectors.
The I
• MCP3424 I
• A2, A1, A0 Address Bits: determined by the JP2 (Adr1 pin) and JP3 (Adr0 pin)
• The JP2 and JP3 connectors are external address bit selections. Connect these
• See Table 1-1 for the I

log 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
