This digital voltmeter circuit is a saving, easy to use Because it is smaller than a typical circuit, I believe that, after I presented this circuit. You will certainly like it. This circuit can be used as Versatile. Features of the circuit : - 3-digit numeric display with LED 7 segment. - The maximum display +999 mV and the maximum negative-99mV. - Adjustment measurement range is not limited by the resistance, only two options. - Using the voltage + 5 V single power supply is not necessary to use the negative circuit pack. The heart in the working of circuit is IC CA3162E. Which converts analog signals into digital signals in a Dual – slope A / D conversion. The output of IC will be the multi-plex binary code display type. so easy to build because has the wire to the display is a few. For the input signal we [...]
