摘要:

该信号发生器以单片机AT89C52和D/A转换器DAC0832芯片为核心进行设计。通过AT89S52控制DAC0832产生所需电流,然后使用运算放大器LF393将其电流输出线性地转换成0~5 V电压输出。通过程序控制,可以产生一系列有规律的波形。该系统具有精度高、抗干扰性强、性能稳定、升级方便等特点,具有较高的应用价值。

关键词: AT89S52, DAC0832, 信号发生器, D/A转换

Abstract:

The signal generator has the microcontroller AT89S52 and D/A converter DAC0832 as the hardcore.Controlled by the AT89S52,DAC0832 produces the required current.Then the operational amplifier LF393 linearly converts the current to a 0~5 V voltage.Through the control of the program,the system can produce a series of regular waves.The system has the advantages of high precision,strong anti-interference,stable performance,easy upgrade and high practical value.

Key words: AT89S52;DAC0832;signal generator;D/A conversion
