The AD5821A is a single, 10-bit digital-to-analog converter (DAC) with output current sinking capability of 120 mA. 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, I2 C®- compatible serial interface that operates at clock rates up to 400 kHz. The AD5821A incorporates a power-on reset circuit that ensures 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 AD5821A is designed for autofocus, image stabilization, and optical zoom applications in camera phones, digital still cameras, and camcorders. The AD5821A is also suitable for many industrial applications, such as controlling temperature, light, and movement without derating over temperatures ranging from −30°C to +85°C. The I2 C 7-bit address for the AD5821A is 0xC.
