[3DMakerWorld] Adafruit MCP4728 Quad DAC with EEPROM - Stemma QT/Qwiic:
$15

Key Features:

• 12-Bit Voltage Output DAC with Four Buffered Outputs
• On-Board Nonvolatile Memory (EEPROM) for DAC Codes and I2Address Bits
• Chose between two sources for your reference voltage - Internal or External Voltage Reference Selection
• STEMMA QT - SparkFun Qwiic connector compatible

If you've ever said to yourself, "Gee, I wish I had four 12-bit DACs that came in a single package with the ability to save their settings to an EEPROM", well I have good news. The MCP4728 is the answer to your wishes! Within its little package, the MCP4728 has four 12-bit DACs for whatever voltage setting needs you may have. In addition, it has the ability to store the settings for the DACs to an internal EEPROM. Once saved to the internal non-volatile memory, the settings will be loaded by default when the DAC powers up. All over I2C!

To take things even further, the MCP4728 lets you chose between two sources for your reference voltage: the input voltage that you use to power it on the VCC pin, or an internal 2.048V reference voltage. If you use the internal reference voltage (Vref in DAC speak) you can choose between 1X or 2X gain for the output, allowing your voltages to range from 0V to 2.048 or 0V to 4.096V as your application requires.
