HiLetgo MCP4725 12 Bit I2C IIC DAC Development Board Breakout Board Internal EEPROM Store Settings for Arduino The MCP4725 is an I2C controlled Digital-to-Analog converter (DAC). A DAC allows you to send analog signal, such as a sine wave, from a digital source, such as the I2C interface on the Arduino microcontroller. On board are SCL, SDA, VCC, and another GND for your basic I2C pinout. If you are looking to have more than one MCP4725 on a bus, the pull-up resistors on this board can be disabled just check the Hookup Guide in the Documents section below for instructions and tips on doing this.store settings Digital to analog converters are greInternal EEPROM to store settingsat for sound generation, musical instruments, and many other creative projects!
