Global Mixed-mode Technology G2034A 120mA, Current Sinking, 10-bit I2C DAC for VCM Driver Features General Description VCM driver for auto-focus The G2034A is single 10bit DAC with 120mA output 10bit resolution current sinking of 120mA for current sink capability. Designed for linear control of VCM voice coil motors, the G2034A is capable of operating VCM slew rate control (SRC) Linear slope voltage to 3.6V. The DAC is controlled via a I2C serial control, Dual level control interface that operates DAC by clock rates up to Supply voltage range (VDD) : 2.3V to 3.6V 400kHz. Fast mode I2C interface (1.8V interface availa- ble) The G2034A incorporates with a power-on reset circuit, Power on reset (POR) power-down function, and exactly matched sense re- TDFN2X2-6 and WLCSP2X3-6 package sistor. Power-on reset circuit ensure when supply power up, DAC output is to 0V Until valid write-bit val- ue takes place. It has a power down features that re- Applications duces the current consumption of the device to 1A Digital camera maximum. Cell phone Lens auto focus The G2034A is designed for auto focus and optical Web camera zoom camera phones, digital still cameras, and cam- corders applications. The I2C address for the G2034A is 0x18. Ordering Information ORDER TEMP.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended pe- riods may affect device reliability. 2. Device are ESD sensitive. Handling precaution recommended. The Human Body model is a 100pF capacitor discharged through a 1.5k resistor into each pin. 3. Using X5R or X7R input capacitors. Electrical Characteristics (VDD= 2.3V to 3.6V, VIN=1.8V to VDD,T =+25C. ) A The device is not guaranteed to function outside its operating conditions. Parameters with MIN and/or MAX limits are 100% tested at +25C, unless otherwise specified.

The output compliance voltage is guaranteed by design and characterization, not mass production test. 2. G2034A requires waiting time of 12ms after power on. During this waiting time, the offset calibration of internal amplifier is operating for minimization of output offset current. 3. Maximum output current can be set 60mA to 130mA.
