Its on-board precision output amplifier allows it to achieve rail-to-rail analog output swing. The DAC input and configuration data can be programmed to the nonvolatile memory (EEPROM) by the user using I2C interface command. The nonvolatile memory feature enables the DAC device to hold the DAC input code during power-off time, and the DAC output is available immediately after power-...
