## Description

The Adafruit MCP4728 Quad DAC with EEPROM provides four independent 12-bit digital-to-analogue converters in a single I2C package. Set precise output voltages for your project, and save your settings to the built-in EEPROM so they're automatically restored on power-up. Each channel supports two voltage reference modes: use the input supply voltage (VCC) for 0–3.3V or 0–5V output, or switch to the internal 2.048V reference with selectable 1× or 2× gain for 0–2.048V or 0–4.096V output ranges. All configuration is done over I2C with no additional components required. Key Features 4× 12-Bit DAC Channels – Independent voltage outputs with 4096-step resolution Built-In EEPROM – Save DAC settings to non-volatile memory for automatic recall on power-up Flexible Voltage Reference – Choose between VCC input or internal 2.048V reference per channel Selectable Gain – 1× or 2× gain with internal reference (0–2.048V or 0–4.096V output) I2C Interface – Simple two-wire communication for easy integration STEMMA QT / Qwiic Ports – Solderless I2C daisy-chaining compatible with Qwiic and Grove (with adapter) 3.3V and 5V Compatible – Works with a wide range of microcontrollers and single-board computers Ideal For Precision voltage control for analogue circuits Calibration and testing setups requiring adjustable reference voltages Audio synthesis and waveform generation Servo and motor control with analogue voltage inputs Package Contents 1× Adafruit MCP4728 Quad DAC Breakout (with STEMMA QT / Qwiic connectors) Tip: Use the internal 2.048V reference with 1× gain for ~3.3V applications, or 2× gain for ~5V applications, for consistent output independent of supply voltage fluctuations.
