The circuit given here is of a very useful and accurate digital voltmeter with LED display using the ICL7107 from Intersil. The ICL7107 is a high performance, low power, 3.5 digit analog to digital converter. The IC includes internal circuitry for seven s

Figure 5 The simple DC digital meter circuit is completely. In Figure 5 is the digital voltmeter circuit designed for general applications. Which it requires the maximum range equal to 200mV. If you want more the voltage range. Which they can do. The circ

The post explains a very simple digital panel type voltmeter circuit using a single IC L7107 and a few other ordinary components. The circuit is able to measure voltages right up to 2000 AC/DC V. About the IC L7107
