The MCP4728 features four 12-bit DACs in a compact package, designed to meet a variety of voltage output requirements. It includes integrated EEPROM that allows you to store device settings, which are automatically loaded at power-up from the non-volatile memory. Communication and configuration are handled via I2C interface. The device supports selection between two reference voltage sources: the external supply voltage on the VCC pin or an internal 2.048V reference. When using the internal reference, users can select a gain of 1X or 2X, enabling output ranges of 0V to 2.048V or 0V to 4.096V, respectively. By default, the input voltage serves as the reference, supporting output ranges up to the supply voltage (e.g., 0V to 3.3V or 0V to 5V). Key Specifications: - 12-bit resolution with four buffered voltage outputs - On-chip EEPROM for storing configuration and I2C address settings - Selectable internal or external voltage reference - Output voltage range options: - Internal VREF (2.048V): - 0.000V to 2.048V (gain = 1) - 0.000V to 4.096V (gain = 2) - External VREF: 0.000V to VCC - Typical differential nonlinearity (DNL): 0.2 LSB - Fast settling time: 6 s (typical) - Operates from a single supply: 2.7V to 5.5V - Default I2C address: 0x60 Color: As shown Material: PCB Note: Product appearance may vary slightly between batches, but this does not affect functionality. Package Contents: 1 x MCP4728 Quad Output Module Kit The package includes only the items listed above. Note: Lighting conditions and display settings may cause slight variations in the color representation between the image and the actual product. Measurement tolerances may vary by 1-3 cm.
