MCP4728 Quad 12-Bit DAC with EEPROM, MSOP-10

The MCP4728 from Microchip is a sophisticated quad, 12-bit voltage output digital-to-analogue converter (DAC) that incorporates non-volatile EEPROM memory. This feature is a key advantage, allowing the device to store DAC input codes, configuration settings, and its I2C address, ensuring these critical parameters are retained and immediately available upon power-up without requiring host reconfiguration. This makes it an invaluable supporting component in complex application networks.

The device features an on-board precision output amplifier that delivers a rail-to-rail analogue output swing, maximising the dynamic range from the single-supply operation of 2.7V to 5.5V. It offers excellent performance with a typical differential nonlinearity (DNL) of just ±0.2 LSB and a fast settling time of 6 µs, enabling rapid and accurate signal generation.
