for Digital Still Cameras
BU24033GW
●General Description
BU24033GW is a system Lens Driver that uses μ-step
driving to make the configuration of the sophisticated,
high precision and low noise lens driver system possible.
This IC has a built-in driver for both DC motor and voice
coil motor and a μ-step controller that decreases CPU
power. Therefore, multifunctional lens can be applied.
