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.\n\nThe 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.\n\nKey Features\n\n\n12-Bit Resolution – 4096 steps of analogue output\n\nI2C Interface – Simple two-wire connection to any microcontroller\n\nRail-to-Rail Output – Proportional to supply voltage (3.3 V or 5 V)\n\nEEPROM – Stores output voltage; restores on power-up\n\nConfigurable Address – A0 pin broken out for running two DACs on one I2C bus\n\nFast Mode I2C – Up to 3.4 Mbps for ~200 kHz output updates (on supported controllers)\n\nBreadboard Friendly – Includes 6-pin header\n\n\nSpecifications\n\n\nDAC: Microchip MCP4725\n\nResolution: 12-bit\n\nInterface: I2C\n\nSupply Voltage: 3.3–5 V\n\nOutput Range: 0 V to VDD (rail-to-rail)\n\n\nPackage Contents\n\n1× MCP4725 12-Bit DAC Breakout Board\n1× 6-pin header\n\n\nResources\n\nMCP4725 DAC Tutorial (Adafruit Learn)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":6607,"title":"Default Title","sku":"AF-935","price":9.9,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":38,"option1":"Default Title"}]}
