摘要
介绍了555时基芯片的功能、主要特性,以及555芯片在0～10Hz、0～10kHz、10Hz～10kHzV/F(电压/频率)转换电路及其在测量中的应用,并给出了实验数据,结果表明,由555芯片组成的转换电路具有价格低、精度高、线性好等特点。
The 555 chip is an widely used IC, it has a lot of applications in many fields, but the application of it in the converter of analog/digital is few. In this paper, the function, main characteristics, and electric circuit of converter and the application to measurement have been introduced . The voltage/frequency converter composed by the 555 chip has many characteristics, such as low cost, high precision, high linear output, wide frequency scope and little peripheral equipment Etc. It is the perfect voltage/frequency converter of synchronous.
