AD9833型高精度可编程波形发生器及其应用

Programmable waveform generator AD9833 and its application

AD9833型可编程波形发生器是一款为各种需要得到高精度正弦波、三角波、方波信号的应用而设计的器件,该器件采用第三代频率合成技术—直接数字频率合成技术,以“相位”的概念进行频率合成,不仅可以产生不同频率的正弦波,而且可以控制波形的初始相位,还可以产生三角波和方波。主要介绍AD9833的基本结构、功能特性及应用。

The AD9833 programmable waveform generator is designed for various situations that require high accurate sine wave, triangular wave and square wave. It is based on the technology of the Ⅲ frequency synthesis Direct Digital Frequency Synthesis technology,which synthesizes frequency from the concept of phase. It can generate sine wave with various frequency, and it could control the initial phase. Also, it can be used as triangular and square wave generator. The configuration, main performance and application information of the AD9833 are introduced in detail.
