The MCP4725 is the DAC that will let you output analog voltages from a microcontroller.Ā The CJMCU-MCP4725 is an I2C controlled Digital-to-Analog converter (DAC).A DAC allows you to send analog signal, such as a sine wave, from a digital source,Ā such as the I2C interface on the forĀ Arduino microcontroller.Ā Digital to analog converters are great forĀ sound generation, musical instruments, and many other creative projects!
Ā
This version of the CJMCU-MCP4725 Breakout fixes a few issues with the board including the IC footprint, the I2C pinout,Ā changes the overall board dimensions to better fit your projects, and a few more minor tweaks.Ā This board breaks out each pin you will need to access andĀ the MCP4725 including GND and Signal OUT pins for connecting to an oscilloscope orĀ any other device you need to hook up to the board.
Also on board are SCL, SDA, VCC, and another GND for your basic I2C pinout.
Additionally, if you are looking to have more than one MCP4725 on a bus,Ā the pull-up resistors on this board can be disabled just check theĀ Hookup Guide in the Documents section below for instructions and tips on doing this.

Features:
12-bit resolution
I2C Interface (Standard, Fast, and High-Speed supported)
It is an I2C controlled 12-bit digital to analog converter that lets a microcontroller output analog voltages. It is a breakout with exposed pins for easy wiring and can generate signals such as sine waves.
What voltage does it operate from?
The device supports a supply from 2.7V to 5.5V.
What I2C features and memory does it include?
It uses an I2C interface with Standard, Fast, and High-Speed modes and includes an internal EEPROM to store settings.
Can I use multiple MCP4725 devices on the same I2C bus?
Yes, you can have more than one on a bus. The pull up resistors on the board can be disabled to accommodate multiple devices, see the Hookup Guide for instructions.
What pins are exposed on the breakout for wiring and testing?
The board exposes GND, VCC, SCL, SDA, and the DAC output pin labeled Signal OUT, plus a second GND for convenience.
