MCP4728 Quad DAC Breakout Board with EEPROM

Adafruit MCP4728 Quad DAC Breakout Board with EEPROM is designed using the Microchip MCP4728, a quad digital-to-analog converter (DAC). The MCP4728 has four 12-bit DACs for whatever voltage setting needs the user has. It can store the settings for the DACs in an internal EEPROM. Once saved to the internal non-volatile memory, the settings will be loaded by default when the DAC powers up. The MCP4728 also lets the user choose between two sources for the reference voltage. The input voltage can be powered on the V_CC pin or an internal 2.048V reference voltage. If the internal reference voltage is used, the user can choose between 1X or 2X gain for the output, allowing the voltages to range from 0V to 2.048 or 0V to 4.096V, as the application requires.
