Applications and Uses of Integrated Circuits
The advantages of Integrated Circuits are:
- Very small size: Hundred times smaller than the discrete circuits.
- Lesser weight: As large number of components can be packed into a single chip, weight is reduced
- Reduced cost: The mass production technique has helped to reduce the price,
- High reliability: Due to absence of soldered connection, few interconnections and small temperature rise failure rate is low.
- Low power requirement: As the size is small power consumption is less.
- Easy replacement: In case of failure chip can easily be replaced.
Because of the above mentioned advantages IC's found numerous applications from cars (automotive controls), televisions, computers, microwaves, portable devices like laptops, MP3, play stations, cameras, cellular phones to ship equipments, aero planes, space craft’s. These are also used in switching telephone circuits and data processing. They also found applications in military equipments. The most common application of IC is digital watch which tells hour, second, minute, day and month. Another common but important application is scientific calculator which can perform basic functions like addition, subtraction, multiplication and division as well as complex functions like square root, cube, permutations, combinations , trigonometric functions, etc
IC's are are of Linear ,digital and mixed types. Linear IC's also known as analog Integrated circuits are used in :
- Power amplifiers
- Small-signal amplifiers
- Operational amplifiers
- Microwave amplifiers
- RF and IF amplifiers
- Voltage comparators
- Radio receivers
- Voltage regulators
Digital IC's are mostly used in computers. They are also referred as switching circuits because their input and output voltages are limited to two levels - high and low i.e. binary. They include:
- Logic gates
- Calculator chips
- Memory chips
- Clock chips
- Temperature sensors
