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 maximum. 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 inclusive.Consumer ApplicationsLens autofocusImage stabilizationOptical zoomShuttersIris/exposureNeutral density (ND) filtersLens coversCamera phonesDigital still camerasCamera modulesDigital video cameras/camcordersCamera-enabled devicesSecurity camerasWeb/PC camerasIndustrial ApplicationsHeater controlFan controlCooler (Peltier) controlSolenoid controlValve controlLinear actuator controlLight controlCurrent loop control
