SparkFun I2C DAC Breakout - MCP4725

The SparkFun I2C DAC Breakout - MCP4725 is a compact, I²C controlled Digital-to-Analog converter (DAC) that enables the output of analog voltages from a microcontroller. This DAC is perfect for projects requiring sound generation, musical instruments, and many other creative applications.

The MCP4725 is designed for ease of use, breaking out each pin for access and usage, including GND and Signal OUT pins for connection to an oscilloscope or any other device. It also includes SCL, SDA, VCC, and another GND for your basic I²C pinout. For those looking to have more than one MCP4725 on a bus, the onboard pull-up resistors can be disabled. Detailed instructions and tips for this are available in the Hookup Guide in the Documents section.

The revised version of the MCP4725 Breakout addresses several issues with the board, including the IC footprint and the I²C pinout. The overall board dimensions have also been adjusted to better accommodate your projects, along with several other minor tweaks.

Key Features:

• 12-bit resolution for precise control
• I²C Interface (Standard, Fast, and High-Speed supported) for versatile connectivity
• Compact design for easy integration into projects
• 2.7V to 5.5V supply for flexible power options
• Internal EEPROM to store settings for convenience
