D/A数字模拟转换模块采用的是DAC0832芯片，该芯片为双列直插20脚封装，最高转换速率为1MHz,管脚定义如3所示。在实验板中，D/A模块输入直接与FPGA相连，输出接口为OUTPUT，由于DAC0832芯片为电流输出，后面跟两级运算放大器将电流输出转换成电压输出，具体电路参见DAC0832数据手册，运放采用TL081芯片。
DAC0832可直接进行数据输出完成DA转换，无需其他控制信号-D/A digital analog conversion module is DAC0832 chip, the chip is 20 pin dual in-line package, the maximum conversion rate of 1MHz, pin as defined in 3 below. In the experiment board, D/A module and the FPGA directly connected to input and output interface for the OUTPUT, as DAC0832 chip current output, followed by two operational amplifiers to convert the current output voltage output, see the DAC0832 data sheet specific circuit, op amp using TL081 chip. DAC0832 data output can be directly completed DA conversion, no additional control signals
