GY-4725 I2C DAC Breakout – MCP4725 digital-analog converter module

Features:

GY-4725 I2C DAC Breakout – MCP4725 digital-analogue converter module

• 12-bit resolution
• I²C Interface (Standard, Fast, and High-Speed supported)
• Small package
• 2.7V to 5.5V supply
• Internal EEPROM to store settings

You’ve always wanted to output analogue 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 analogue signal, such as a sine wave, from a digital source, such as the I²C interface on the Arduino microcontroller. Digital to analogue converters are great for sound generation, musical instruments, and many other creative projects!

This version of the GY-4725 I2C DAC Breakout – MCP4725 digital-analogue converter module 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

Does a DAC really improve the sound?

Despite making your music sound better, one of the key improvements a DAC will make may be less obvious at first. A high-quality DAC will help you achieve a cleaner sonic background, improving the overall soundstage of your listening setup and creating a wider, deeper listening scape.

Why do I need a DAC converter?

Any time you want to listen to a digital audio signal (like an MP3 or the audio from a digital video) through an analogue output (like wired headphones and speakers), you need a DAC to convert the digital signal from the source into an analogue signal at the point of connection. … This is why you need a separate DAC.
