Hi Seetharaman, Can you pls design a PCB for this lovely Circuit, or if you have one already,where can i download the same.

Digital voltmeter using ICL – Electronic Circuits and Diagrams-Electronic Projects and Design

Capacitor C2 neutralizes the fluctuations in the internal reference voltage and increases the stability of the display. Convert current into mV by using a suitable conditioning resistance to measure D. Then a known reference voltage of opposite polarity is applied to the adtasheet of ucl7107cpl integrator and allowed to ramp until the output of integrator becomes zero. Modify it to accept 0 to 1. Hi, with so many complaints of thsi circuit I think I might not should trust this electronics engineeeeeeeeer!

Hi Seetharaman, Any Circuit on the above, but suitable for measuring Amp.

How cani get -5V from my o-9v adapter?????? Assemble the circuit on a good quality PCB. Hi Patrick a nice one you can use it. Hi all, I made a PCB using a artwork sent by ejhgbb gmail. Hi Zernab go through the following site for full details http: I was told that these are the ext. I need help on this. The IC includes internal circuitry for seven segment decoders, display drivers, reference voltage source and a clock. Audio oscillator circuit Simple function generator circuit Digital thermometer circuit Capacitance meter using LM Frequency to voltage converter using LM We recommend: I assembled this circuit few years back and it is still working fine.


Can you pls design a PCB for this lovely Circuit, or if you have one already,where can i download the same. Can I use this circuit to measure V AC? In simple words, the input voltage is compared to an internal reference voltage and the result is converted in a digital format.

ICL7106, ICL7107 3 1/2 Digit A/D Converter

I beeternot build this,NO? Please anyone help me. Hi MJ use NE and generate-5volt from 9volt see the following site.

Hi Mahamoud please go through jcl7107cpl intersil datasheet for your requirement http: The thing is displaying erroneous values. I need pcb layout of digital voltmeter using ic The pin5 representing the dot is connected to ground only for the third display and its position needs to be changed when you datxsheet the range of the volt meter by altering R4.

I made a digital voltmeter with ICL but display is not stable please help datashet. Thearmocouple sensor connect to Kindly go through Intersil datasheet which is more informative http: For switching ranges used 4 pole 3 way rotary switch, first pole changes resistor and second pole moves decimal point pin 5 on indicator from D1 at v DC to D3 ie v DC.

Thanks for pointing the mistake. R4 controls the range of the voltmeter. Somebody pls tell me… Does the tolerance of the capacitors used matter??

Will this circuit work on breadboard? What is the recommended input voltage which is connected in R5 pin numbers 30 and 31?. The voltage to be measured is converted into a digital equivalent by the ADC inside the IC icl7107cpk then this digital equivalent is decoded to the seven segment format and then displayed. I completly removed R4, but it is not working linearely… Anybody tryed to use the V range?


Feel free to send your PCB image to john datasyeet. Right most three displays are connected so that they can display all digits.

The power dissipation is less than 10mW and the display stability is very high. For a fixed period of time the voltage to be measured is integrated to obtain a ramp at the output of the integrator. I sent an email listing all of the errors and omissions I found when building this voltmeter which I thought would be useful to the constructors who were having problems but adtasheet has edited them out of my comments, why?

I assembled the circuit, dataaheet only icl7107cpo 7seven segment is glowing, rest are glowing with very low brightness and its unreadable. And how will it affect the circuit?? There is given for DC voltage measurement,is it possible to measure for AC also or any modifications are required please give me suggestion.

You may also like: Hi Rohit the basic meter is datashset to measure 0 — R5 and R4 are input potential divider. PIN5 is the decimal point!! R1 is for the decimal point indication, hence no relevance on the measurement of voltage. The working of this electronic circuit is very simple.

The process taking place inside our ADC can be stated as follows. Built this cct yesterday and it works really well.
