The MCP4726A3T-E/CH is a single-channel, 12-bit Digital-to-Analog Converter (DAC) featuring a buffered voltage output, nonvolatile EEPROM memory, and an I2C serial interface. It operates from a single 2.7V to 5.5V supply and provides a rail-to-rail buffered voltage output with a typical fast settling time of 6 µs. The device includes on-board nonvolatile EEPROM, allowing the DAC register and configuration settings to be saved and automatically recalled on power-up. Communication is handled via an I2C-compatible serial interface supporting modes up to 3.4 Mbps, with this specific model configured for I2C address '1100011'. Its features make it well-suited for applications such as set point or offset trimming, sensor calibration, and low-power portable instrumentation.
