AD8303集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

AD8303属于集成电路（IC）的数模转换器（DAC）。由亚德诺半导体技术有限公司制造生产的AD8303数模转换器（DAC）数模转换器（DAC、D/A、D2A 或 D 转 A）可将数字信号转换为缓冲或无缓冲的模拟电压或电流。DAC 架构是否适合特定应用，要取决于分辨率和采样频率。DAC 通常用于音乐播放器，将数字数据流转换为模拟音频流。它们还用于电视和手机，将数字视频数据转换为模拟视频信号，再连接到屏幕驱动器，以显示单色或彩色图像。

GENERAL DESCRIPTION

The AD8303 is a complete (includes internal reference) dual,12-bit, voltage output digital-to-analog converter designed to operate from a single +3 volt supply. Built using a CBCMOSprocess, this monolithic DAC offers the user low cost and ease of-use in single-supply +3 volt systems. Operation is guaranteed over the supply voltage range of +2.7 V to +5.5 V making this device ideal for battery operated applications.The 2.0475 V full-scale voltage output is laser-trimmed to maintain accuracy over the operating temperature range of the device. The binary input data format provides an easy-to-use one-half millivolt-per-bit software programmability. The voltage outputs are capable of sourcing 3 mA.
