Datasheet (MCP4725)Product Overview
While most microcontrollers simulate an analog 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 analog 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 analog generation with non-volatile memory and straightforward I2C integration, this breakout ensures your microcontroller can handle analog tasks efficiently and consistently.
