INTRODUCTION
DESCRIPTION OF THE MCP4728 EVALUATION BOARD
The following sections provide an overview of the MCP4728 Evaluation Board and
instructions on how to program the DAC register and the EEPROM of the MCP4728
using the PICkit
• Description of the MCP4728 Evaluation Board
• How to use the MCP4728 Evaluation Board with the PICkit Serial Analyzer
The purpose of the MCP4728 Evaluation Board is to provide an easy way of evaluating
the MCP4728’s performance and functionality with a minimum of work.
The MCP4728 Evaluation Board contains a MCP4728 (which is a 4-channel, 12-bit
Digital-to-Analog Converter), an interface connector for the PICkit Serial Analyzer, and
I
Analyzer or by providing the I
terminals.
Using the MCP4728 Evaluation Board, the user can evaluate the functionality of the
MCP4728 device, such as: (a) Writing and reading the DAC registers and EEPROM of
each channel, (b) Selecting the reference voltage, (c) Measuring the DAC output
voltage, (d) Checking the LDAC pin feature, etc.
The MCP4728 Evaluation Board is designed to work friendly with the PICkit Serial
Analyzer (DV164122). The PICkit Serial Analyzer (P/N: DV164122) is used for writing
and reading the DAC configuration and register data. The PICkit Serial Analyzer
consists of hardware and PC GUI. It is highly recommended that the users order this
MCP4728 Evaluation Board and the PICkit Serial Analyzer at same time.
