AD7303集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

AD7303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AD7303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 AD7303 is a dual, 8-bit voltage out DAC that operates from a single +2.7 V to +5.5 V supply. Its on-chip precision output buffers allow the DAC outputs to swing rail to rail. This device uses a versatile 3-wire serial interface that operates at clock rates up to 30 MHz, and is compatible with QSPI, SPI, microwire and digital signal processor interface standards. The serial input register is sixteen bits wide; 8 bits act as data bits for the DACs, and the remaining eight bits make up a control register.
