This is a link to your datasheet for the ICL7107 chip you are using. Here is the schematic diagram of digital DC voltmeter built based IC ICL7107. Digital voltmeter circuit diagram using ICL7107 / 7106 with PCB Let's build Simple ICL7017 digital voltmeter circuit easy to build and cheap. You may use 9V battery and then use regulator IC LM7805 to achieve 5V stabilized voltage. Here is the schematic diagram of digital DC voltmeter built based IC ICL7107. Simple Digital Voltmeter Circuit Diagram using ICL7107 In this project we build a low cost and accurate Digital Voltmeter circuit on PCB using a popular IC for voltage measurement namely ICL7107/CS7107. It is a perfect addition to any DIY laboratory power supply, battery chargers and other electronic projects where voltage and current consumption must be monitored. This circuit will be good to display your power supply output. The power supply for this circuit is +5V. Circuit Diagram of Digital Voltmeter Because it is high technology with single IC on 7 segment LED. Here is the schematic diagram of digital DC voltmeter built based IC ICL7107. Use the data sheets and you will understand, as pointed out, why it is very important to use the parts called out in the drawing, especially the capacitor values. The power supply for this circuit is +5V. You may use 9V battery and then use regulator IC LM7805 to achieve 5V stabilized voltage. LM3914 is a 10 stage voltmeter that means it shows variations in 10 bit mode. You may use 9V battery and then use regulator IC LM7805 to achieve 5V stabilized voltage. The chip senses the measuring input voltage as a parameter and compares it with reference, every time the voltage crosses the certain part of reference the corresponding LED glows. Here we design a analog to digital converter working as a digital voltmeter using a low power three and half digit A/D converter ICL7107 having internal 7 segment decoders, display drivers, a reference and a clock.
Components List: R1 = … A typical digital voltmeter consists of a analog to digital converter and a digital display. This Voltmeter Ammeter was designed to measure output voltage of 0-70V / 0-500V with 100mV resolution and 0-10A or more current with 10mA resolution. You may use 9V battery and then use regulator IC LM7805 to achieve 5V stabilized voltage. The power supply for this circuit is +5V. This circuit will be good to display your power supply output.
