The WT7024 is a constant current sink driver with a single 10-bit DAC. It provides with max 120mA output current sink capability, and is intended for driving voice coil actuators. The DAC is controlled using the industry-standard I2C 2-wire serial protocol. Data can be written to the DAC, or read back from it, via the interface at clock rates up to 400kHz.In applications, the WT7024 is suitable for lens optical zooming and lens auto-focus in digital still cameras and camera phones.
