Overview

The MCP4728EV is an evaluation board designed to demonstrate the features of the MCP4728, a quad-channel 12-bit voltage output digital-to-analog converter. This board allows engineers to interface with the DAC via a standard I2C bus to test its 6us settling time and non-volatile memory features. It provides a simple platform for verifying multi-channel analog output performance before final hardware integration.

Why Choose This Part

This evaluation tool provides access to all four channels of the MCP4728 with minimal setup, supporting the integrated EEPROM for storing power-on reset states. Its I2C interface simplifies connection to common microcontrollers, while the 12-bit resolution across four channels offers a high density of analog outputs in a small footprint.

Applications

Multi-Channel Setpoint Control
Providing independent 12-bit reference voltages for four separate control loops in industrial systems.
Sensor Calibration
Generating precise analog offset and gain correction signals for sensor signal conditioning chains.
Power Supply Trimming
Using the four DAC channels to digitally tune the output voltage of multiple DC-DC regulators.

Getting Started

Connect the board to an I2C-capable microcontroller like an Arduino or PIC using the provided headers. Ensure the pull-up resistors are correctly configured for your bus voltage and use a logic analyzer or oscilloscope to verify the 6us settling time on the analog outputs. Microchip provides example code and the PICkit Serial Analyzer can be used for PC-based testing without writing custom firmware.
