AD9704集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

AD9704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AD9704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 AD9704/AD9705/AD9706/AD9707 are the fourthgeneration family in the TxDAC series of high performance, CMOS digital-to-analog converters (DACs). This pin-compatible, 8–/10–/12–/14–bit resolution family is optimized for low power operation, while maintaining excellent dynamic performance.
