## Description

The MCP4725 breakout board provides a 12-bit digital-to-analogue converter (DAC) over I2C. Send a digital value and the VOUT pin outputs the corresponding analogue voltage — ideal for generating waveforms, adjustable bias points, or anywhere you need a true analogue output rather than PWM. The output is rail-to-rail and proportional to the supply voltage: 0–3.3 V when powered at 3.3 V, or 0–5 V at 5 V. An onboard EEPROM stores the last output value, automatically restoring it after a power cycle. Key Features 12-Bit Resolution – 4096 steps of analogue output I2C Interface – Simple two-wire connection to any microcontroller Rail-to-Rail Output – Proportional to supply voltage (3.3 V or 5 V) EEPROM – Stores output voltage; restores on power-up Configurable Address – A0 pin broken out for running two DACs on one I2C bus Fast Mode I2C – Up to 3.4 Mbps for ~200 kHz output updates (on supported controllers) Breadboard Friendly – Includes 6-pin header Specifications DAC: Microchip MCP4725 Resolution: 12-bit Interface: I2C Supply Voltage: 3.3–5 V Output Range: 0 V to VDD (rail-to-rail) Package Contents 1× MCP4725 12-Bit DAC Breakout Board 1× 6-pin header Resources MCP4725 DAC Tutorial (Adafruit Learn)
