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.
