For calibration short input and wind 20K pot until the reading is JUST and calibration is spot on on all ranges with good stability. Kindly go through the following datasheet for 0 — 20VDC FS you have to use potential divider in the input. Leave a Reply Cancel reply Your email address will not be published. R1 is for the decimal point indication, hence no relevance on the measurement of voltage. Built this cct yesterday and it works really well.
R4 controls the range of the voltmeter. You may also like: And how will it affect the circuit??
Please anyone help me. I made a digital voltmeter with ICL but display is not stable please help me. Audio oscillator circuit Simple function generator circuit Digital thermometer circuit Capacitance meter using LM Frequency to voltage converter using LM There is given for DC voltage measurement,is it possible to measure for AC also or any modifications are required please give me suggestion.
Modify it to accept 0 to 1. Previous post Next post. I assembled this circuit few years back and it is still working fine. PIN5 is the decimal point!! Hi Patrick a nice one you can use it. Can you help me with a schematic diagram of a digital meter that can measure ampere 0AA pls. The power dissipation is less than 10mW and the display stability is very high.
Hi Seetharaman, Can you pls design a PCB for this lovely Circuit, or if you have one already,where can i download the same. Use RS website for data sheets. Somebody pls tell me… Does the tolerance of the capacitors used matter?? In simple words, the input voltage is compared to an internal reference voltage and the result is converted in a digital format. The thing is displaying erroneous values.
For a fixed period of time the voltage to be measured is integrated to obtain a ramp at the output of the integrator. The seven segment displays must ico7107cpl common anode type. How cani get -5V from my o-9v adapter?????? I was told that these are the ext. Hi Seetharaman, Any Circuit on the above, but suitable for measuring Amp.
I need pcb layout of digital voltmeter using ic Can I use this circuit to measure V AC? Hi Zernab go through the following site for full details http: Kindly go through Intersil datasheet which is more informative http: Your email address will not be published.
In the above circuit the maximum reading can be Capacitor C2 neutralizes the fluctuations in the internal reference icl77107cpl and increases the stability of the display.

Are you shure that decreasing the value for R4 you increase the range? Can you pls design a Icl7107pcl for this lovely Circuit, or if you have one already,where can i download the same. I need help on this. Right most three displays are connected so that they can display all digits.
ICL7106, ICL7107 3 1/2 Digit A/D Converter
I assembled the circuit, but only third 7seven segment is glowing, rest are glowing with very low brightness and its unreadable. I completly removed R4, but it is not working linearely… Anybody tryed to use the V range? 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.
