AD5372集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

AD5372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AD5372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 AD5372/AD5373 contain 32 16-/14-bit DACs in 64-lead LQFP and LFCSP packages. The devices provide buffered voltage outputs with a nominal span of 4× the reference voltage. The gain and offset of each DAC can be independently trimmed to remove errors. For even greater flexibility, the device is divided into four groups of eight DACs. Two offset DACs allow the output range of the groups to be altered. Group 0 can be adjusted by Offset DAC 0, and Group 1 to group 3 can be adjusted by Offset DAC 1. The AD5372/AD5373 offer guaranteed operation over a wide supply range: VSSfrom −16.5 V to −4.5 V and VDD from 9 V to 16.5 V. The output amplifier headroom requirement is 1.4 Voperating with a load current of 1 mA.
