摘 要
本數(shù)字電壓表所采用的芯片是TC14433。該簡易數(shù)字電壓表可以測量0～2V范圍內(nèi)的輸入電壓值，并在4位LED數(shù)碼管上輪流顯示或單路選擇顯示。另一方面，精度也從0.1%提高到了現(xiàn)在的0.01%——0.005%，而且從實驗空用的高價的所謂的樣品開始已發(fā)展到了現(xiàn)在廠礦企業(yè)廣為利用的所謂的廉價型，進而出現(xiàn)了能夠用于安裝板上作指示儀表的安裝型。
本文首先對基于TC14433數(shù)字電壓表的背景和國際研究做了簡要概述，讓人們更直觀的發(fā)現(xiàn)該設(shè)計的優(yōu)點。接著介紹了TC14433的引腳功用和一些元件的作用，對電路的原理和結(jié)構(gòu)做了簡要的說明，并且通過DS1—DS4控制數(shù)碼管將電壓值顯示在LED數(shù)碼管上，還提供了一些設(shè)計所需的理論數(shù)據(jù)，最后總結(jié)了故障的測試方法和結(jié)論。該項設(shè)計具有廣泛的發(fā)展前途，相信在今后的舞臺上會占有一席之地。
本設(shè)計詳細描述了數(shù)字電壓表的測試與顯示。其主要器件為芯片TC14433，用TC14433完成電壓電壓的A\D轉(zhuǎn)換，再經(jīng)過CD4543B譯碼,用一個反相驅(qū)動器1413芯片驅(qū)動數(shù)碼管顯示. 即CD4543B鎖存—譯碼和共陽極LED發(fā)光數(shù)碼管組成是將被測模擬量轉(zhuǎn)換為數(shù)字量，并進行實時數(shù)字顯示的系統(tǒng)。

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.
