Although most of the products that are made today use some digital component, analog is still viable. In order to convert analog signals to be understood by digital components, they must be converted into ones and zeros. If you think about how computers were initially made, it was the only way to communicate information. These were also called yes and no variables, ones that could lead to higher forms of communication when it came to computers and other components. Here is a quick overview of what analog means, and how this particular technology, though archaic, can still interact with integrated circuits today.

Analog Versus Digital

Looking at this from the perspective of waveforms, this is where you will see the most difference. Analog is like a sinuous waveform, whereas digital is much more square. From a recording perspective, specifically looking at audio, analog refers to the recording of how the original sounds actually were. When Digital first came out, there was a concern that it would not sound proper because it was actually modifying the original sound at a rate where it could be recorded digitally. Fortunately, this technology has improved over the years. When you are using a Blu-ray player, or even DVDs, this is all the result of digital technology. You are literally digitizing natural sound waves into something that is replicated to mimic actual sound.

How Does This Apply To Integrated Circuits?

If you think about how computers, they are literally a series of on and off switches. These are considered to be digital values. They can actually form a language, similar to hexadecimal language, which can be representative of many things like different colors. Integrated circuits use this digital technology to quickly compute information. It is the only way that integrated circuits can function, and therefore they are going to operate in a digital format.

What About Analog Integrated Circuits?

Although digital integrated circuits are used for such things as RAM, microprocessors, and FPGAs, analog ICs are used as active filters, phase locked loops, and linear regulators. Analog systems are focused not so much on data, but on power dissipation, power gain and resistance. There is far less circuitry used with analog systems, and it is in this manner that they are utilized with any modern digital device.

When you are looking for integrated circuits, most people are going to focus on the digital ones that will involve field programmable gate arrays, memory, and microprocessors. They are also involved with ASCII code. However, you will also need to use analog integrated circuits for handling oscillations and as linear regulators. They are simply different and serve a vital purpose. If you are new to creating computers or any other type of electronic product, you will likely come across these as part of the schematic that you must use. Now that you know a little bit more about them, you can see that they are useful but very different from the typical digital technology that is often discussed in regard to modern-day computers.
