Description: 本作品采用DAC0832作为电压信号输出。DAC0832是一款采用CMOS工艺制成的单片电流输出型8位数 / 模转换器。DAC0832有三种工作方式：不带缓冲工作方式，单缓冲工作方式，双缓冲工作方式。因为输出电压量程为10V，VREF基准电压范围为-10V---+10V，基准电压可以为5.12V，这样在DAC0832的8脚输出电压的分辨率为：即D/A输入数据端每增加1，电压增加0.02V。D/A的电压输出端接放大器OP27的输入端，放大器的放大倍数为5 ，才能得到输出电压的电压分辨率：0.02V×5=0.1V这样当调节电压的时候，以每次0.1V的梯度增加或者降低电压。(This work uses DAC0832 as a voltage signal output. The DAC0832 is a monolithic current output 8-bit digital-to-analog converter fabricated in a CMOS process. The DAC0832 has three operating modes: no buffering, single buffering, and double buffering. Because the output voltage range is 10V, VREF reference voltage range is -10V---+10V, the reference voltage can be 5.12V, so that the resolution of the 8-pin output voltage of the DAC0832 is: that is, every D/A input data terminal increases by 1 The voltage increases by 0.02V. The voltage output of D/A is terminated to the input of amplifier OP27. The amplification of the amplifier is 5 to obtain the voltage resolution of the output voltage: 0.02V*5=0.1V. When the voltage is adjusted, it is 0.1V at a time. The gradient increases or decreases the voltage.)

Description: In electronics, an analog-to-digital converter (ADC, A/D, or A-to-D) is a system that converts an analog signal, such as a sound picked up by a microphone or light entering a digital camera, into a digital signal. An ADC may also provide an isolated measurement such as an electronic device that converts an input analog voltage or current to a digital number representing the magnitude of the voltage or current.
