MCP4728A1T-E/UN Description

The MCP4728A1T-E/UN is a quad, 12-bit voltage output Digital-to-Analog Converter (DAC) with nonvolatile memory (EEPROM). Its onboard precision output amplifier allows it to achieve rail-to-rail analog output swing. The DAC input codes, device configuration bits, and I²C address bits are programmable to the nonvolatile memory (EEPROM) using I2C serial interface commands. The nonvolatile memory feature enables the DAC device to hold the DAC input codes during the power-off time, allowing the DAC outputs to be available immediately after power-up with the saved settings.
