Tel：886-3-5645656 Fax：886-3-5645626 VM147 VM147 110mA, 10-Bit Current Sinking VCM Driver with I2C Interface General Specifications The VM147 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 VM147 is designed for applications such as image stabilization, auto-focus, optical zoom in camera phones, and other portable module devices.

Page1 VM147 Terminology Resolution The DAC resolution is defined by the power factor of 2, which defines the number of distinct digitized levels.
N-bit resolution -> 2N distinct digitized levels Differential Nonlinearity (DNL) error The variation in digitized step value away from 1 LSB by any two adjacent digitized levels, gain and offset errors removed.
