摘要:在现代电子学的各个领域，常常需要高精度且频率可方便调节的信号发生器。频率越高、产生波形种类越多的发生器性能越好，但器件成本和技术要求也大大提高，因此在满足工作要求的前提下，性价比高的发生器是我们的首选。本文在介绍Maxim公司MAX038芯片基本特性的基础上，论述了采用MAX038芯片来设计多波形函数信号发生器的原理以及整体的结构设计。辅以控制软件和外围电路的设计，组成一个低成本、多功能、高精度、输出频率高且连续可调的智能信号发生器。

Abstract：In all areas of modern electronics, it often requires high-precision frequency signal generator which can be easily adjusted. The higher frequency and more types of waveform is better generator performance. But the device cost and technical requirements are also greatly improved. Therefore, to meet the work requirements under the premise, the cost-effective generator is our first choice.In this paper, based on the Maxim MAX038 chip characteristics, it discusses the MAX038 chip design principle of the multi-waveform function signal generator and the overall structural design. Supplemented by the control software and peripheral circuit design, this paper composed of a intelligent signal generator which is low-cost, multi-function, high accuracy, the output frequency is continuously adjustable.
