AD9715集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

AD9715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AD9715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 AD9714/AD9715/AD9716/AD9717 are pin-compatible dual, 8-/10-/12-/14-bit, low power digital-to-analog converters (DACs) that provide a sample rate of 125 MSPS. These TxDAC® converters are optimized for the transmit signal path of communication systems. All the devices share the same interface, LFCSP package, and pinout, providing an upward or downward component selection path based on performance, resolution, and cost. The AD9714/AD9715/AD9716/AD9717 offer exceptional ac and dc performance and support update rates up to 125 MSPS. The flexible power supply operating range of 1.8 V to 3.3 V and low power dissipation of the AD9714/AD9715/AD9716/AD9717 make them well-suited for portable and low power applications.
