Product Summary

The MCP4728-E/UN is a Quad Digital-to-Analog Converter. The MCP4728-E/UN is a quad, 12-bit voltage output Digital-to-Analog Convertor (DAC) with non-volatile memory (EEPROM). Its on-board precision output amplifier allows it to achieve rail-to-rail analog output swing. The MCP4728-E/UN has a high precision internal voltage reference (VREF = 2.048V). The user can select the internal reference or external reference (VDD) for each channel individually.The applications of the MCP4728-E/UN include Set Point or Offset Adjustment, Sensor Calibration, Closed-Loop Servo Control, Low Power Portable Instrumentation, PC Peripherals, Programmable Voltage and Current Source, Industrial Process Control and Instrumentation.
