FUNCTIONAL BLOCK DIAGRAM
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 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 max.
The AD5398 is designed for autofocus, image stabilization,
and optical zoom applications in camera phones, digital still
cameras, and camcorders.
The AD5398 also has many industrial applications, such as
controlling temperature, light, and movement, over the range
−40°C to +85°C without derating.
The I2C address range for the AD5398 is 0x18 to 0x1F
