11-MD218A
130mA, 10-Bit Current Sinking VCM Driver
with I2C Interface
General Specifications
The 11-MD218A is a VCM driver IC with I2C interface control that is capable of
programmable output current sinking. It has a built-in internal voltage reference and
operates in a wide supply voltage range from 2.4V to 5.5V. The DAC is controlled by a
2-wire I2C serial interface which operates in I2C fast mode (400 kHz). The 11-MD218A is
designed for applications like image stabilization, auto-focus, and optical zoom in camera
phones, digital still cameras, and other portable module devices.
