Boardoza MCP4725 12-Bit I²C DAC Breakout Board
The MCP4725 is a low-power, high accuracy, single channel, 12-bit buffered voltage output Digital-toAnalog Convertor (DAC) with non-volatile memory (EEPROM). 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 non-volatile memory (EEPROM) by the user using I2C interface command. The non-volatile 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-up.
I2C address bit selection pin (A0 bit) is connected to GND by default.
