Dfrobot DFR0552 DFR0552 I2C 12-Bit DAC Module for Arduino and Raspberry Pi Board

Gravity I2C 12bit DAC module is a small and easy-to-use 12bit digital-to-analogue converter with EEPROM. It can accurately convert the digital value to corresponding analogue voltage signal which is useful in may creative projects and automatic control systems. Although an analogue voltage signal can be generated by PWM with traditional controllers such as Arduino and Raspberry Pi, such signal is rough and not accurate. To obtain a steady and nice analogue voltage signal, the DAC is the best candidate. In addition to be applied in automatic control systems, the DAC module can be used to serve as a function generator to generate sine, triangular and even arbitrary waveform. The module employs a 12bit DAC MCP4725. It requires no external reference voltage (DAC reference is driven from VCC directly). The EEPROM can retain the DAC input while power-off and resume the DAC output upon power-on. Typical application includes sensor calibration, automatic control systems, function generator.
