GETTING STARTED WITH PICKIT SERIAL ANALYZER
Figure 1-1 shows the MCP3421 SOT23-6 Evaluation Board and Figure 1-2 shows the
Evaluation Board and PICkit Serial Analyzer connection.
The following steps describe how to use them together:
1. Connect the MCP3421 SOT23-6 Evaluation Board’s J1 pin socket to the PICkit
2. Connect the oscilloscope probes to SCL and SDA test pins (optional).
3. V
4. Connect V
5. LED D1 turns on when V
6. Connecting analog inputs: If you need to measure single-ended input, connect
7. Use the PICkit Serial Analyzer PC GUI to send I
8. Execute the PICkit Serial Analyzer Script file and obtain the ADC conversion
The analog input pin has ESD diodes. Certain input conditions can damage the
device. Please pay attention to the following conditions:
