In order to meet the higher requirements on frequency and resolution technology indexes in the audio data acquisition process,this paper proposes a high speed data acquisition device.This design uses the Altera company's Cyclone series EP1C4F400 FPGA chip to control the AD7762 A/D converter by the ADI company and realizes data acquisition using Verilog language in QuartusⅡ environment.Serial port is used to transmit data to the PC,which accomplishes the function of data analysis and display.FPGA controls the acquisition timing of the whole system.

Key words: data acquisition;AD7762;FPGA;register control;serial port
