+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.
