The inexpensive module (shown above) provides easy access to the MCP4725 12-bit DAC. According to the official datasheet, the device address contains four fixed bits (device code = 1100) and three ...

The MCP4725 is an I2C single channel 12 bit Digital to Analog Converter (DAC). It is possible to have up to 8 MCP4725 on one I2C bus. The MCP4725 supports 100 KHz 400 KHz and 3.4 MHz bus speeds. The ...

Arduino driver for the DAC7578 8-channel 12-bit digital-to-analog converter (DAC). The DAC7578 from Texas Instruments is an 8-channel 12-bit DAC with an I²C interface designed for applications such as ...

Here I test the current-source with 12-bit DACs from Microchip. At first I tested the I2C DAC MCP4725, but the result was not so good: 3 to 6 mV offset (expected 0...1 mV), also the linearity was bad.
