描述
The RAA305315GBM is a general-purpose Optical Image Stabilization (OIS) driver IC. This compact, single-chip IC integrates a 32-bit RISC microcomputer and DSP in the control block, along with the hall signal processing circuit and VCM driver in the driver block. It supports both open and closed-loop autofocus (AF) control.
