Description: You’ve always wanted to output analog voltages from a microcontroller, the MCP4725 is the DAC that will let you do it! The 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, such as the I2C interface on the Arduino microcontroller. Digital to analog converters are great for sound generation, musical instruments, and many other creative projects!
This version of the MCP4725 Breakout fixes a few issues with the board including the IC footprint, the I2C pinout, changes the overall board dimensions to better fit your projects, and a few more minor tweaks. This board breaks out each pin you will need to access and use the MCP4725 including GND and Signal OUT pins for connecting to an oscilloscope or 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, the pull-up resistors on this board can be disabled just check the Hookup Guide in the Documents section below for instructions and tips on doing this.

This works just like it is suppose too! The components selected and the options available make them easy to integrate into a prototyping environment. It certainly beats having to solder the chip to a breakout board then trying to properly place components before using. Hmm, a 10uf tantalum along with the .1uf ceramic power supply line would have been nice.
This breakout is ideal for verifying analog channels of my designs. The processor is already connected up to the motor driver assembly and something isn’t going according to plan; a quick wiring job on the breadboard and the analog sensor problem is history. This breakout board is easy to hook up to troubleshoot concerns with analog inputs with great accuracy; no fuss and/or mess. I would recommend this part to folks dealing with all those analog distance sensors.
