Introduction

The DW9710 is single 8-bit DAC with 127mA output current sink capability. Designed for linear control of voice coil motors, the DW9710 is capable of operating voltage to 5.5V. The DAC is controlled via a I2C serial interface that operates DAC by clock rates up to 400kHz. The DW9710 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 DW9710 is designed for auto focus and optical zoom camera phones, digital still cameras, and camcorders applications. The I2C address for the DW9710 is 0x18.
