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.
