AD5532B集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

AD5532B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AD5532B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 AD5532B is a 32-channel, voltage output, 14-bit DAC with an additional precision infinite sample-and-hold mode. The selected DAC register is written to via the 3-wire serial interface and VOUT for this DAC is then updated to reflect the new contents of the DAC register. DAC selection is accomplished via address bits A0–A4. The output voltage range is determined by the offset voltage at the OFFS_IN pin and the gain of the output amplifier. It is restricted to a range from VSS + 2 V to VDD – 2 V because of the headroom of the output amplifier.
