INTRODUCTION
DESCRIPTION OF THE MCP3422 EVALUATION BOARD
The following sections provide an overview of the MCP3422 Evaluation Board and
demonstrate how to use it with the PICkit™ Serial Analyzer (P/N: DV164122).
The following topics are covered:
• Description of the MCP3422 Evaluation Board
• How to use the MCP3422 Evaluation Board with the PICkit Serial Analyzer
The MCP3422 Evaluation Board (P/N MCP3422EV) contains a MCP3422 18-Bit
Delta-Sigma Analog-to-Digital Converter (ADC). The MCP3422 is a 2-channel ADC
device with various options. The MCP3422 Evaluation Board has analog input
connection pads and V
test the conversion results using the PICkit Serial Analyzer and its PC graphic user
interface (GUI). The MCP3422 Evaluation Board has the following interface:
• PICkit Serial Analyzer for writing configuration register bits and reading the
The user can monitor the I
SDA and SCL test pads. Refer to Appendix A. “Schematic and Layouts”.
