AD5348BRU-REEL集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

AD5348BRU-REEL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AD5348BRU-REEL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。

CGENERAL DESCRIPTION

The AD5346/AD5347/AD53481 are octal 8-,10-,and 12-bit DACs,operating froma 2.5 V to 5.5 V supply. These devices incorporatean on-chipoutput buffer that can drive the output to both supply rails, and also allow a choice of buffered or unbuffered reference input.
