The function of an IC (integrated circuit) chip is to replace many separate electronic components which could possibly have been used to build a particular electronic circuit. Most of those separate components are replaced by just one tiny IC chip that has been manufactured ("fabricated" is the correct technical word) to include extremely miniature circuits which imitate the behavior of all those separate components.
- There are many reasons why ICs are being used more and more. Here are just a few of them:
- costs of manufacture: using an IC saves the labor of soldering together all the separate components to make the equivalent circuit
- space: using an IC saves the huge amount of space that the circuit would take up if it were built using separate components
- energy: using an IC saves a lot of electrical energy compared to the same circuit built using separate components
- speed: using an IC makes the circuit work much faster than it could ever do if it were built using separate components.
An IC chip can include tens, hundreds, thousands or many millions of components. ICs are commonly used nowadays to build computers and many other types of electronic devices.
