New and high quality! Product Overview The MCP4728 is a compact, four-channel 12-bit digital-to-analog converter (DAC) that offers flexible voltage configuration for a wide range of applications. Each DAC channel supports programmable output voltages, and settings can be stored in the built-in EEPROM for non-volatile retention. Upon power-up, the device automatically loads these saved configurations, ensuring consistent performance without reprogramming. All operations are performed via the I2C bus, providing simple and efficient communication with microcontrollers. The MCP4728 supports two reference voltage options: the external supply voltage (VCC) or an integrated 2.048 V reference. When using the internal reference, you can select a gain of 1× or 2×, allowing output ranges of 0–2.048 V or 0–4.096 V, respectively. If the external VCC is used as the reference, the output can be scaled from 0 V up to 3.3 V or 5 V, making it suitable for both 3.3 V and 5 V systems. Ideal for precision analog control, sensor calibration, adjustable power supplies, and embedded systems, the MCP4728 combines high accuracy, compact size, and ease of integration into your designs.
