Basic Integrated circuit

Introduction:- Any electronic circuit is uses different types of operation like amplification , generating oscillation, modulation, demodulation, comparing two signals, adding binary numbers, storing some binary number like many other operations.
All these operation required some components like transistor diode resistance capacitor etc. All these components are fixed on a PCB as per drawing then by giving operating supply and output load connection circuit start working.

Integrated circuit:- The required operating function circuit is design in a single package that is known as integrated circuit as all components are integrated. ICs come in single in line package and duel in line packages. Surface mount ICs are very commen now a days in mobile phone and computer dvd cd payer etc. Main thing to note is this each IC has a uniqe number which gives the details of that IC function. Basically we can divide all ICs in three categaries. first is audio amplifier, video amplifier, operation amplifier all theses are analog ICs. IC used for adder, comparator, microcontoller, microprocesser, sd card, ram, pen drive etc are works  on digital data so they all are known as digital ICs. All digital circuit work on 5 volt dc or 3.3 volt dc. All digital ICs are works on TTL logic. Anolog ICs for different functions comes in different operating voltage that we should check with the data sheet of that IC.
For a complete fuction we can get a single IC, we have to fix IC and few components on PCB and circuit becomes complete. Many assembled modules are also available for amplifiers and other things. It is a very brief idea about ICs for beginners.
