DESCRIPTION
The EUM6820 can operates from 2.3V to 5.5V. The EUM6820 incorporates a power-on reset circuit, which ensures that DAC output powers up to 0V and remains there until a valid write takes place. It has a power-down feature that reduces the current consumption of the device to 1µA maximum. The EUM6820 principally designed for linear control of voice coil motors, targeting at autofocus, image stabilization, and optical zoom applications in camera phones , digital still cameras, and camcorders. While it may also used in many industrial applications, such as controlling temperature, light, and movement. The I2C address for the EUM6820 is 0 × 18. FEATURES
