AD5337BRM-REEL7集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

AD5337BRM-REEL7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AD5337BRM-REEL7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 AD5337/AD5338/AD5339 are dual 8-, 10-, and 12-bit buffered voltage output DACs, respectively. Each part is housed in an 8-lead MSOP package and operates from a single 2.5 V to 5.5 V supply, consuming 250 μA at 3 V. On-chip output amplifiers allow rail-to-rail output swing with a slew rate of 0.7 V/μs. A 2-wire serial interface operates at clock rates up to 400 kHz. This interface is SMBus compatible at VDD
