Is there an IC that ouput the input voltage in BCD? I want to make a voltmeter that can display the voltage in decimal number.
david90 said:the a/d chip on that site uses multiplexing to power the 7 seg led. How does that work? THe chip turn the led on and off so fast that our eyes won't see the flickering?
A voltmeter IC is an integrated circuit that is specifically designed to accurately measure voltage in a binary-coded decimal (BCD) format. It is typically used in electronic devices to monitor and display voltage levels.
A voltmeter IC works by converting the analog voltage signal into a digital signal. It then uses a BCD decoder to convert the digital signal into a BCD format which is displayed on the output pins of the IC.
One of the main advantages of using a voltmeter IC is its high accuracy and precision in measuring voltage levels. It also requires very few external components, making it cost-effective and easy to use. Additionally, it has a wide measurement range and can handle both AC and DC voltages.
Some voltmeter ICs have the capability to measure other parameters such as current, resistance, and temperature. However, the majority of voltmeter ICs are specifically designed for measuring voltage and may not have the necessary components to accurately measure other parameters.
When choosing a voltmeter IC, it is important to consider the required measurement range, accuracy, and resolution for your specific application. Additionally, you should also consider the supply voltage, input impedance, and any additional features that may be necessary for your project.
