GENERAL DESCRIPTION

The AD5398A is a single, 10-bit digital-to-analog converter

(DAC) with a current sink output capability of 120 mA. This

device 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 (1.8 V, I²C®-compatible) serial interface that operates

at clock rates up to 400 kHz.

Available in 3 × 3 array WLCSP package

APPLICATIONS

Consumer

Lens autofocus

Image stabilization

Optical zoom

Shutters

Iris/exposure

Neutral density (ND) filters

Lens covers

The AD5398A incorporates a power-on reset circuit, which

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 0.5 μA

typically.

Camera phones

The AD5398A is designed for autofocus, image stabilization,

and optical zoom applications in camera phones, digital still

cameras, and camcorders. The AD5398A 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 I²C address range for the

AD5398A is 0x18 to 0x1F inclusive.
