11-VM148

130mA, 10-Bit Current Sinking VCM Driver

with I

2C Interface

General Specifications

The 11-VM148 is a VCM(Voice Coil Motor) driver IC with I2C interface control that is

capable of programmable sinking output current. It has a built-in internal voltage reference

and operates with a supply voltage range from 2.4V to 5.5V. The DAC is controlled by a

signal transmit through a 2-wire I2C serial interface which operates in an I2C fast mode

(400 kHz). The 11-VM148 is designed for applications such as image stabilization,

auto-focus, optical zoom in camera phones, and other portable module devices.
