SparkFun Qwiic 12 Bit DAC Breakout - MCP4725

The SparkFun MCP4725 Qwiic DAC Breakout provides true 12-bit analogue voltage output over I2C, making it ideal for signal generation, calibration, audio projects, and other applications where PWM isn't precise enough. While most microcontrollers simulate an analogue voltage using Pulse Width Modulation (PWM) to create a digital square wave, many projects require a smoother signal. The SparkFun MCP4725 Qwiic 12 Bit DAC Breakout allows you to get precise voltage outputs from a microcontroller over a Qwiic connection. This Digital-to-Analog Converter is an excellent choice for applications where PWM simply falls short, offering the precision needed for demanding electronics projects. Smooth Signal Generation: Deliver clean voltage signals for sound generation, custom musical instruments, or sensitive analogue actuators. Standard Resolution: The 12-bit resolution provides 4,096 precise voltage steps between GND and VCC (2.7V to 5.5V), giving you precise control over your hardware. Onboard Memory: Features internal non-volatile memory (EEPROM) that allows you to store a specific voltage setting. Upon power-up, the DAC immediately outputs the stored level, making it highly effective for set-and-forget calibration or reliable voltage-reference applications. Simplified Solderless Integration This DAC breakout board uses the Qwiic Connect System, featuring a pair of Qwiic connectors for instant, solderless I2C communication and power delivery. For those of you integrating the board into custom layouts or breadboards, standard 0.1-inch-spaced plated-through-hole (PTH) pins are also broken out for VCC, GND, SDA, SCL, and the MCP4725's Signal OUT pin. By combining true analogue generation with non-volatile memory and straightforward I2C integration, this breakout ensures your microcontroller can handle analogue tasks efficiently and consistently.
