This article describes the High Noise Immunity for Data Transmission with VFC CIRCUIT (TC9400). The content is very simple, very helpful. Components in this article can help you understand better understanding of this article. For example, in this article, you can go to find and buy these components:TC9400.

It is advantageous to convert the analog signal into a digital signal, which is less susceptible to noise pick-up when transmitting analog data over long distances. It is very easy for noise to interfere the amplitude of a signal, but it would be harder to change its frequency.

HIGH NOISE IMMUNITY DATA TRANSMISSION1 circuit schematic

The TC9400 converts the input voltage into a pulse or square wave which is transmitted on a pair of wires by use of a line driver and receiver in the following system. At the other end, we can digitally displayed the original voltage (Vin) on a frequency counter or converted back to an analog voltage by use of a TC9400 F/V converter.
