    Description

    Product Description
    The MCP4725 is an easy-to-use 12-bit Digital-to-Analog Converter (DAC) that allows a microcontroller to generate true analog voltage output using a simple I2C interface. This breakout board converts digital values into smooth analog voltages, making it ideal for applications where PWM is not suitable, such as audio signals, waveform generation, adjustable reference voltages, and analog control systems.

    The output voltage is rail-to-rail and directly proportional to the supply voltage. When powered at 3.3V, the output range is 0–3.3V, and when powered at 5V, the output range is 0–5V. The onboard EEPROM allows the last output value to be stored so that the DAC restores the same voltage automatically after power-up.

    This module includes a STEMMA QT / Qwiic compatible JST-SH 4-pin connector, enabling solder-free, plug-and-play connection with Arduino, Raspberry Pi, ESP32, STM32, and other I2C-enabled platforms. Standard 0.1-inch header pins are also provided for breadboard or custom wiring.

    Key Features

    • 12-bit resolution DAC (4096 steps)

    • True analog voltage output (not PWM)

    • I2C interface for simple control

    • Onboard EEPROM to store output voltage

    • Rail-to-rail output proportional to supply voltage

    • Supports two DACs on one I2C bus using address selection

    • STEMMA QT / Qwiic compatible for solder-free connection

    Technical Specifications

    • DAC Resolution: 12-bit

    • Interface: I2C

    • I2C Address: 0x60 (default), configurable via A0 pin

    • Operating Voltage: 3.3V or 5V

    • Output Voltage Range: 0V to VCC

    • Fast Mode I2C Support: Up to 3.4 Mbps (device dependent)

    • Non-volatile Memory: Onboard EEPROM

    Typical Applications

    • Analog signal generation (sine, triangle, ramp)

    • Audio and waveform experiments

    • Adjustable reference or bias voltage

    • Sensor simulation and calibration

    • Robotics and control systems

    Package Contents

    • 1 × MCP4725 12-Bit DAC Breakout Module

    This MCP4725 breakout is a simple, reliable, and compact solution for adding high-quality analog output to any I2C-based embedded project while supporting modern STEMMA QT / Qwiic plug-and-play wiring.
