µ-step System Lens Driver

for Digital Still Cameras

BU24035GW

General Description

Key Specifications

BU24035GW is a system Lens Driver which is capable of

µ-step driving and possible to configure a high precision

and low noise lens driver system. This device performs

µ-step driving control internally and can reduce a load of

CPU. This device also has drivers for DC motor and

voice coil motor, and is utilizable for multifunctional lens.
