摘 要
本数字电压表所采用的芯片是TC14433。该简易数字电压表可以测量0～2V范围内的输入电压值，并在4位LED数码管上轮流显示或单路选择显示。另一方面，精度也从0.1%提高到了现在的0.01%——0.005%，而且从实验空用的高价的所谓的样品开始已发展到了现在厂矿企业广为利用的所谓的廉价型，进而出现了能够用于安装板上作指示仪表的安装型。
本文首先对基于TC14433数字电压表的背景和国际研究做了简要概述，让人们更直观的发现该设计的优点。接着介绍了TC14433的引脚功用和一些元件的作用，对电路的原理和结构做了简要的说明，并且通过DS1—DS4控制数码管将电压值显示在LED数码管上，还提供了一些设计所需的理论数据，最后总结了故障的测试方法和结论。该项设计具有广泛的发展前途，相信在今后的舞台上会占有一席之地。
本设计详细描述了数字电压表的测试与显示。其主要器件为芯片TC14433，用TC14433完成电压电压的A\D转换，再经过CD4543B译码,用一个反相驱动器1413芯片驱动数码管显示. 即CD4543B锁存—译码和共阳极LED发光数码管组成是将被测模拟量转换为数字量，并进行实时数字显示的系统。

Abstract
The digital voltmeter of the chip is TC14433 chip, the chip has small volume, light weight, low cost advantages. This simple digital voltmeter can measure 0 ~ 2 V within the scope of the input voltage values, and in the four LED digital display or taking turns on the single option to show. On the other hand, the precision can also increased from 0.1% to 0.01% now-0.005%, and from the experiment with the high price of empty the sample of the so-called has now widely use of mines the so-called cheap type, and can be used to install board appeared on the installation instructions type.
This paper based on TC14433 digital voltmeter background and international research is briefly introduced, and let people more intuitive found that the design advantages. Then it introduces the TC14433 pin function and some components function, to the circuit principle and structure did briefly, and through the DS1-DS4 control digital tube will be displayed in voltage LED digital tube, and also provides some design in the required theoretical data, finally summarized the fault of the testing method and the conclusion. The design has wide development outlook, believe that in the future holds a place on the stage.
This design detailed descriptions of the digital voltmeter test and display. The main device for chip TC14433, complete with TC14433 voltage voltage of A \ D conversion, and then after CD4543B decoding, with A reverse phase drive 1413 chip drive digital pipe display. That is CD4543B latch-decoding of anode and LED digital tube composition is being measured analog conversion for the digital quantity, and the real-time digital display system.
Key words: TC14433 A \ D convert digital pipe display
