AD5370集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

AD5370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AD5370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 AD5370 contains forty 16-bit DACs in a single 64-lead LFCSP and a 64-lead LQFP. The device provides buffered voltage outputs with a span that is 4× the reference voltage. The gain and offset of each DAC channel can be independently trimmed to remove errors. For even greater flexibility, the device is divided into five groups of eight DACs. Three offset DAC channels allow the output range of blocks to be adjusted. Group 0 can be adjusted by Offset DAC 0, Group 1 can be adjusted by Offset DAC 1, and Group 2 to Group 4 can be adjusted by Offset DAC 2. The AD5370 offers guaranteed operation over a wide supply range, with VSSfrom −16.5 V to −4.5 V and VDDfrom +9 V to +16.5 V. The output amplifier headroom requirement is 1.4 V operating with a load current of 1 mA.
