产品概述 返回TOP
The CXMD3291 is a single 10-bit DAC with 120mA output current sink capability. It operates from 2.3V to 5.0V supply. The DAC is controlled via 2-wire (I2C-compatible) serial interface that operates at clock rates up to 400kHz. The CXMD3291 provides a power-down mode. The power-down mode can be enabled by PD pin or I2C interface. At power-down mode, the output current reduces to 1μA maximum. The CXMD3291 is designed for autofocus, image stabilization, and optical zoom applications in camera modules.
