PIN5 is the decimal point!! By my logic, I shoud be in the oposit… I want to make an amperpeter, I need the smallest range V.

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

Modify it to accept 0 to 1. R5 and R4 are input potential divider. R1 is for the decimal point indication, hence no relevance on the measurement of voltage.

Thanks for pointing the mistake. Hi Patrick a nice one you can use it. For a fixed period of time the voltage to be measured is integrated to obtain a ramp at the output of the integrator. Hi all, I made a PCB using a artwork sent by ejhgbb gmail. Kindly go through the following datasheet for 0 icl71077cpl 20VDC FS you have to use potential divider in the input.

ICLCPL Datasheet(PDF) – Intersil Corporation

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


This voltmeater is working precisely. Hi MJ use NE and generate-5volt from 9volt see the following site. I completly removed R4, but it is not working linearely… Anybody tryed to use the V range? Please anyone help me.

Datashdet adjust R6 so that the display reads 0V. You may also like: Built this cct yesterday and it works really well. Somebody pls tell me… Does the tolerance of the capacitors used matter?? I made a digital voltmeter with ICL but display is not stable please help me. Datashset simple words, the input voltage is compared to an internal reference voltage and the result is converted in a digital format.

The ICL is a high performance, low power, 3. Hello A similar project is available with PCB and the works, do check the same. For calibration short input and wind 20K pot until the reading is JUST and calibration is spot on on all ranges with good stability.

How cani get -5V from my o-9v adapter?????? The process taking place inside our ADC can be stated as follows. Thearmocouple sensor connect to Audio oscillator circuit Simple function generator circuit Digital thermometer circuit Capacitance meter using LM Frequency to voltage converter using LM Hi Zernab go through the following site for full details http: Hi Adnan If your final drive devices have open Icl7107cll collector then you require common anode display such that the required segment can be pulled to ground for glowing.

Previous post Next ic7107cpl. Leave a Reply Cancel reply Your email address will not be published.

I beeternot build this,NO? The thing is displaying erroneous values. Hi Seetharaman, Can you pls design a PCB for this lovely Circuit, or if you have one already,where can i download the same. So avoid touching the IC pins with your bare hands. Can you pls design dataheet PCB for this lovely Circuit, or if you have one already,where can i download the same. Can you help me with a schematic diagram of a digital meter that can measure iccl7107cpl 0AA pls.


The IC includes internal circuitry for seven segment decoders, display drivers, reference voltage source and a clock. Convert icl7107pcl into mV by using a suitable conditioning resistance to measure D. I assembled the circuit, but only third 7seven segment is glowing, rest are glowing with very low brightness and its unreadable.

I was told that these are the ext.

ICLCPL-3 datasheet, Pinout ,application circuits ICL, ICL 3 1/2 Digit A/D Converter

Assemble the circuit on a good quality PCB. 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. Can I use this circuit to measure V AC? In the above circuit the maximum reading can be 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.

Hi Mahamoud please go through the intersil datasheet for your requirement http: Will this circuit work on breadboard?

Right most three displays are connected so that they can display all digits.
