+description: |-
+ The Dongwoon DW9768 is a single 10-bit digital-to-analog (DAC) converter
+ with 100 mA output current sink capability. VCM current is controlled with
+ a linear mode driver. The DAC is controlled via a 2-wire (I2C-compatible)
+ serial interface that operates at clock rates up to 1MHz. This chip
+ integrates Advanced Actuator Control (AAC) technology and is intended for
+ driving voice coil lenses in camera modules.
