So avoid touching the IC pins with your bare hands. The power dissipation is less than 10mW and the display stability is very high. There is given for DC voltage measurement,is it possible to measure for AC also or any modifications are required please give me suggestion. How cani get -5V from my o-9v adapter?????? The working of this electronic circuit is very simple.

Hi, with so many complaints of thsi circuit I think I might not should trust this electronics engineeeeeeeeer! The IC includes internal circuitry for seven segment decoders, display drivers, reference voltage source and a clock. In the above circuit the maximum reading can be Feel free to send your PCB image to john circuitstoday. I completly removed R4, but it is not working linearely… Anybody tryed to use the V range?

For switching ranges used dxtasheet 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 icl107cpl v DC.

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

Audio oscillator circuit Simple function generator circuit Digital thermometer circuit Capacitance meter using LM Frequency to voltage converter using LM We recommend: Can I use this circuit to measure V AC? PIN5 is the decimal point!! Assemble the circuit on a good quality PCB.

Use RS website for data sheets. Right most three displays are connected so that they can display all digits.

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

Hi Rohit the basic meter is designed to measure 0 lcl7107cpl I need help on this. R5 and R4 are input potential divider.

Hi Seetharaman, Can you pls design a PCB for this lovely Circuit, or if you have one already,where can i download the same. Built this cct yesterday and it works really well. The ICL is a high performance, low power, 3. R1 is for the decimal point indication, hence no relevance on the measurement of voltage.

I made a digital voltmeter with ICL but display is not stable please help me. Then adjust R6 so that the display reads 0V.

Hi Zernab go through the following site for full details http: The pin5 representing the dot is connected to ground only for the third display and its position needs to be changed when you change the range of the volt meter by altering R4. Please anyone help me. I assembled the circuit, but only third 7seven segment is glowing, rest are glowing with very low brightness and its unreadable.

Hi MJ use NE and generate-5volt from 9volt see the following site. You may also like: Thanks for pointing the mistake. For a fixed period of time the voltage to be measured is integrated to obtain a ramp at the output icl7107cppl the integrator. The seven segment displays must by common anode type. I need pcb layout of digital voltmeter using ic By my logic, I shoud be in the oposit… I want to make an amperpeter, I need the smallest range Datashert.


The thing is displaying erroneous values. The process taking place inside our ADC can be stated as follows. In case if your final drive device can give high output with suffucient drive current, then you require a common cathode disply such that when ever the disply input goes high that particular segment will glow.

CPL Datasheet ETC pdf data sheet FREE from

The voltage to be measured is converted into a digital equivalent by the ADC inside the IC and then this digital equivalent is decoded to the seven segment format and then displayed. Then a known reference voltage of opposite polarity is applied to the input of icl7107xpl integrator and allowed to ramp until the output of integrator becomes zero.

This voltmeater is working precisely.

Can you pls design a PCB for this lovely Circuit, or if you have one already,where can i download the same. R4 controls the range of the voltmeter. I beeternot build this,NO? Will this circuit work on breadboard?
