Part Details:

120 mA, Current Sinking, 10-Bit, I2C® DAC AD5821 FEATURES INDUSTRIAL APPLICATIONS 120 mA current sink Heater controls Available in 3 × 3 array WLCSP package Fan controls 2-wire (I2C-compatible) 1.8 V serial interface Cooler (Peltier) controls 10-bit resolution Solenoid controls Integrated current sense resistor Valve controls 2.7 V to 5.5 V power supply Linear actuator controls Guaranteed monotonic over all codes Light controls Power-down to 0.5 A typical Current loop controls Internal reference Ultralow noise preamplifier GENERAL DESCRIPTION Power-down function The AD5821 is a single 10-bit digital-to-analog converter with Power-on reset 120 mA output current sink capability. It features an internal reference and operates from a single 2.7 V to 5.5 V supply. CONSUMER APPLICATIONS The DAC is controlled via a 2-wire (I2C-compatible) serial Lens autofocus interface that operates at clock rates up to 400 kHz. Image stabilization The AD5821 incorporates a power-on reset circuit that ensures Optical zoom that the DAC output powers up to 0 V and remains there until Shutters a valid write takes place. It has a power-down feature that reduces Iris/exposure the current consumption of the device to 1 A maximum. Neutral density (ND) filters Lens covers The AD5821 is designed for autofocus, image stabilization, and Camera phones optical zoom applications in camera phones, digital still cameras, Digital still cameras and camcorders. Camera modules The AD5821 also has many industrial applications, such as Digital video cameras/camcorders controlling temperature, light, and movement, over the range of Camera-enabled devices -40°C to +85°C without derating. Security cameras The I2C address for the AD5821 is 0x18.
