Design of low frequency sine signal generator based on ML2037

Zhang Li-yun

Abstract

This paper takes ML2037 as the core technology designs a low frequency sine signal generator which is controlled by MCU STC11F.It describes the principle of DDS technology and the design principles of this system hardware and software.The system works in a single 5V power supply.It can generate highly precise sine wave with highest frequency 391kHz,the frequency and amplitude are adjustable,it possessed of stable performance,simple circuit and low price.
