AD5382集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

AD5382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AD5382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 AD5382 is a complete, single-supply, 32-channel, 14-bit denseDAC® available in a 100-lead LQFP package. All 32 channels have an on-chip output amplifier with rail-to-rail operation. The AD5382 includes an internal software-selectable 1.25 V/2.5 V, 10 ppm/°C reference, an on-chip channel monitor function that multiplexes the analog outputs to a common MON_OUT pin for external monitoring, and an output amplifier boost mode that allows optimization of the amplifier slew rate.
