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 ...

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 ...

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.
