| 摘 要： | 介绍了基于AD9833的信号发生器的设计方案。由单片机AT89S52完成系统的控制功能；幅度控制采用AD8320可编程增益放大器和D／A转换芯片TLC7528实现：功率放大电路采用高速缓冲器BUF634。最大可输出250mA的电流。实验表明该系统能够产生正弦波、方波和三角波三种周期性波形，且能实现从1Hz-2MHz的稳定输出，频率稳定度优于10^-4。

| Abstract: | The design of signal generator based on AD9833 is proposed in this paper. The single-chip microcomputer AT89S52 is adopted in control module. The prograrnmable gain ampLifier AD8320 and D/A converter TLC7528 are used in ampLitude control module. The high speed buffer BUF634 is introduced in power amplifier, and its maximum output current is 250mA. The experiment results indicate the system can produce sine wave, square wave and triangular wave. The frequency range is 1Hz-2MHz. The frequency stability surpasses 10^-4. |
