The IC's are made using 'micro-electronics' technology which reduces the size of components to about one tenth or even smaller as compared to their discrete type. So an IC is a micro electronic circuit. Electronic circuits such as an amplifier etc. can be made inside an IC using microelectric technology.
It has a small size, cheap cost circuiting and it consists of active and passive components which are connected to each other on a small single chip which is made of silicon material.
IC's have complicated circuit built in small space with more reliability.
Power consumption is low.
Higher operating speed.
Less weight and compact size.
If an IC becomes faulty, it has to be replaced.
Capacitors more than 30 pF can't be fabricated.
They are very delicate and need careful handling.
Limited power dissipation.
Initial cost is high.
Resistors with more than 100 KQ can't be fabricated in IC's.
Direct fabrication of inductors not possible.
Higher temperature coefficient.
