Analog Devices AD5823
the AD5823 SHUTDOWN pin is active low; the AD5823-1 SHUTDOWN pin is active high. The AD5823/AD5823-1 were designed for autofocus applications in camera modules, camera phones, digital still cameras, and camcorders. The AD5823/AD5823-1 have many industrial applications, such as controlling temperature, light, and movement over the temperature range of −40°C to +85°C without derating.

The AD58231 and AD5823-1 are single, 10-bit DACs with 100 mA output current sink capability and integrated Actuator Response Control™ (ARC™) technology. ARC is a revolutionary autofocus capture time and image quality enhancing technology developed by Analog Devices, Inc., and integrated into the AD5823/AD5823-1 VCM drivers. ARC circuitry applies specialized, patented waveform and application technology to underdamped voice coil motors (VCMs) to reduce mechanical ringing.
