AD5821ABCBZ-REEL7

AD5821A is a single, 10bit digital-to-analogue converter. The DAC is controlled via a 2-wire, I²C®-compatible serial interface that operates at clock rates up to 400KHz. It incorporates a power-on reset circuit that ensures the DAC output powers up to 0V and remains there until a valid write takes place. It is designed for autofocus, image stabilization, and optical zoom applications in camera phones, digital still cameras, and camcorders. It is also suitable for many industrial applications, such as controlling temperature, light. Application includes lens autofocus, image stabilization, optical zoom, shutters, iris/exposure, neutral density filters, lens covers, camera phones, digital still cameras, camera modules, digital video, cameras/camcorders, camera-enabled devices, security cameras, web/PC cameras, heater controls, fan controls, cooler controls, solenoid controls, valve controls, linear actuator controls, light controls, current loop controls (industrial).

• 120mA maximum sink current (VDD = 2.7V to 5.5V, AGND = DGND = 0V)
• 2-wire, (I²C-compatible) 1.8V serial interface
• Integrated current sense resistor, guaranteed monotonic over all codes
• Power supply range from 2.7V to 5.5V
