+
+description:
+  The LC898217XC is a 11-bit digital-to-analog (DAC) converter.
+  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.
