G2034AG21U     WLCSP2X3-6

120mA, Current Sinking, 10-bit I2C DAC for VCM Driver

General Description

The G2034A is single 10bit DAC with 120mA output

current sink capability. Designed for linear control of

voice coil motors, the G2034A is capable of operating

voltage to 3.6V. The DAC is controlled via a I2C serial

interface that operates DAC by clock rates up to

400kHz.

The G2034A incorporates with a power-on reset circuit,

power-down function, and exactly matched sense resistor.

Power-on reset circuit ensure when supply

power up, DAC output is to 0V Until valid write-bit value

takes place. It has a power down features that reduces

the current consumption of the device to 1μA

maximum.

The G2034A is designed for auto focus and optical

zoom camera phones, digital still cameras, and camcorders

applications. The I2C address for the G2034A

is 0x18.
