   产品概述 返回TOPZIx嘉泰姆

The CXMD3278 is single 10-bit DAC with 150mA output current sink capability. Designed for linear control of voice coil motors, the CXMD3278 is capable of operating voltage from 2.3V to 5.5V. The DAC is controlled via a I2C serial interface that operates DAC by clock rates up to 400kHz. The CXMD3278 incorporates with a UVLO reset circuit, power-down function, and exactly matched sense resistor. UVLO 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 1uA maximum. The CXMD3278 is designed for auto focus and optical zoom camera phones, digital still cameras, and camcorders applications. The I2C address for the CXMD3278 is 0x18.
