INTRODUCTION
DESCRIPTION OF THE MCP3424 EVALUATION BOARD
The following sections provide an overview of the MCP3424 Evaluation Board and
demonstrate how to use it with using the PICkit™ Serial Analyzer (P/N: DV164122).
The following topics are covered:
• Description of the MCP3424 Evaluation Board
• How to use MCP3424 Evaluation Board with the PICkit Serial Analyzer
The MCP3424 Evaluation Board (P/N MCP3424EV) contains an MCP3424 18-bit
Delta-Sigma Analog-to-Digital Converter (ADC). The MCP3424 is a 4-channel ADC
device with various configuration options. The board has analog input connection pads
and various test pads. The user can connect inputs and test the conversion results
using the PICkit Serial Analyzer and its PC graphic user interface (GUI). The MCP3424
Evaluation Board has the following interfaces:
• PICkit Serial Analyzer (P/N: DV164122) for writing configuration register bits and
The board has test points for SDL, SDA, and analog inputs. By connecting an oscillo-
scope to these test points, the user can examine the data communications through the
