Units – DAC Unit MCP4725 I2C DAC Converter



Description

DAC, like its namesake, is a high performance digital/analog signal convertor. Build with MCP4725,which is a low-power, high accuracy, single channel, 12-bit buffered voltage output Digital-to-Analog Convertor (DAC) with non-volatile memory(EEPROM).

Same as ADC, DAC communicates with I2C. The address is 0x60.
