Hello friends, I hope you all are doing great. Today, I am going to share the new MCP4725 DAC Module Library for Proteus , the first of the lab ICs in our University Lab series. A DAC, a digital-to-analog converter, does the opposite of the Arduino's analogRead: it takes a number and turns it into a real voltage. The Arduino UNO has no true DAC of its own; its analogWrite is only PWM, a fast on-off square wave. The MCP4725 adds a genuine 12-bit analog output over two I2C wires, and that is why it is everywhere in student labs: programmable reference voltages, sensor calibration, function generators, audio tones, motor and LED control, and closed-loop experiments.
