10. What is Integrated Circuit (IC)
If multiple electronic components are interconnected on a single chip of
semiconductor material, then that chip is called as an Integrated Circuit (IC). It
consists of both active and passive components.

11. Advantages of Integrated Circuits
 Compact size - For a given functionality, you can obtain a circuit of smaller
size using ICs, compared to that built using a discrete circuit.
 Lesser weight - A circuit built with ICs weighs lesser when compared to the
weight of a discrete circuit that is used for implementing the same function of
IC. using ICs, compared to that built using a discrete circuit.
 Low power consumption - ICs consume lower power than a traditional circuit,
because of their smaller size and construction.

12. Contd..
 Reduced cost - ICs are available at much reduced cost than discrete circuits
because of their fabrication technologies and usage of lesser material than
discrete circuits.
 Increased reliability - Since they employ lesser connections, ICs offer
increased reliability compared to digital circuits.
 Improved operating speeds - ICs operate at improved speeds because of their
switching speeds and lesser power consumption.

14. Analog Integrated Circuits
8/5/2020 14
Integrated circuits that operate over an entire range of continuous values of the signal
amplitude are called as Analog Integrated Circuits. These are further classified into
the two types as discussed here
Linear Integrated Circuits - An analog IC is said to be Linear, if there exists a linear
relation between its voltage and current. IC 741, an 8-pin Dual In-line Package
(DIP)op-amp, is an example of Linear IC.
Radio Frequency Integrated Circuits - An analog IC is said to be Non-Linear, if
there exists a non-linear relation between its voltage and current. A Non-Linear IC is
also called as Radio Frequency IC.

15. Digital Integrated Circuits
 If the integrated circuits operate only at a few pre-defined levels instead of
operating for an entire range of continuous values of the signal amplitude, then
those are called as Digital Integrated Circuits.
 In the coming chapters, we will discuss about various Linear Integrated Circuits
and their applications.
