AD5398:  120 mA, Current Sinking, 10-Bit, I²C D/A Converter

The AD5398 is a single 10-bit DAC 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 AD5398 incorporates a power-on reset circuit, which ensures that the DAC output powers-up to zero and remains there until a valid write takes place. It also has a power-down feature that reduces the current consumption of the device to 1 µA max.

The AD5398 is designed for autofocus, image stabilization and optical zoom applications in camera phones, digital still cameras and camcorders.

The I²C address range for the AD5398 is 18 Hex to 1F Hex inclusive.
