The MCP4728 device is a quad 12-bit voltage output Digital-to-Analog Convertor (DAC) with non-volatile memory (EEPROM). The user can program the DAC input codes, device configuration bits, and I2C address bits to the non-volatile memory (EEPROM) by using I2C™Compatible interface commands. The non-volatile memory feature enables the DAC device to hold the DAC input codes during power-off time, allowing the DAC outputs to be available immediately after power-up.
