Adafruit MCP4728 Quad DAC with EEPROM - STEMMA QT / Qwiic

The MCP4728 is the perfect solution if you've ever wished for four 12-bit DACs in a single package with the ability to save settings to EEPROM. This compact device provides four high-precision DACs, each capable of outputting voltage settings, and it includes internal EEPROM for storing these settings. Once saved, the settings are automatically loaded when the DAC powers up, all through a convenient I2C interface.

Key Features:

• Four 12-bit DACs: Perfect for precise voltage control in various applications.
• Internal EEPROM: Saves DAC settings and loads them automatically on power-up.
• Selectable Reference Voltage: Choose between the input voltage or an internal 2.048V reference voltage.
• Gain Options: Set output range with 1X or 2X gain, allowing for voltage ranges of 0V to 2.048V or 0V to 4.096V depending on your application needs.
• Flexible Voltage Scaling: Use the input voltage (3.3V or 5V) as your reference for scaling, or opt for the 2.048V reference for ~3.3V, and 4.096V for ~5V.
• I2C Interface: Communicates easily with your microcontroller or Blinka-supported computer.
• STEMMA QT Connector: Simplifies connecting to your project with a Qwiic compatible JST SH connector.

The breakout board comes fully assembled with the necessary support circuitry, making it easy to integrate with your project. While a QT cable is not included, we offer a variety of STEMMA QT cables in the shop for seamless connections with other compatible sensors and devices.
