The MCP4728 I2C DAC IC with an on board power boost and rail to rail signal amplifier is used to convert the 0-5V output of the DAC to a 0-10V DAC signal with 12-bit resolution and 1% accuracy. It is also possible to share two DACs of this type on the same bus, and the I2C address can be changed by plugging or removing the I2C address jumper. If more than two of these DAC modules are needed, it is advised to use an I2C multiplexer controller to connect multiple of these DAC modules with one I2C master device.
Three modes of operation are supported: standard (100kbps), fast (400kbps), and high speed (3.4Mbps). This module is compatible with Raspberry Pi, Arduino, Onion Omega, Beaglebone, Windows, and Particle Photon.
