摘　　要：本文先阐述了ADC转换器的基本概念、分类以及ADC转换器的主要技术指标,然后介绍了ADS7945芯片的特性,并给出了操作ADS7945芯片的时序图,接着使用Altera公司的FPGA芯片根据ADS7945芯片的时序图编写了满足时序的Verilog代码来完成对ADS7945的控制,最后通过信号源给出了一个正弦波信号来验证所写Verilog代码是否能够控制ADS7945芯片采集模拟量。结论得出所写Verilog代码能够完成对ADS7945的控制,能够成功的从ADS7945得到所采集的数据。The basic concepts of ADC converter,classification and major technical indicators of the ADC were described along with the characteristics of the chip ADS7945,and the timing chart of ADS7945 was given,then the Verilog Language was written in the module to meet the timing chart of ADS7945 to control ADS7945. Finally,the control was verified through a sine wave generated from the signal source. Experiments show that the module can successfully control the ADS7945 and obtain the required data.
