AD5398A:  120 mA, Current Sinking, 10-Bit, I2C DAC

Product Details

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.

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.

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.
