The AD5821 is a single 10-bit digital-to-analog converter with 120 mA output current sink capability. It features an internal reference and operates from a single 2.7 V to 5.5 V supply. The DAC is controlled via a 2-wire (I2C-compatible) serial interface that operates at clock rates up to 400 kHz.

The AD5821 incorporates a power-on reset circuit that ensures that the DAC output powers up to 0 V and remains there until a valid write takes place. It has a power-down feature that reduces the current consumption of the device to 1 µA maximum.

The AD5821 is designed for autofocus, image stabilization, and optical zoom applications in camera phones, digital still cameras, and camcorders.

The AD5821 also has many industrial applications, such as controlling temperature, light, and movement, over the range of −40°C to +85°C without derating.

The I2C address for the AD5821 is 0x18.
