This eBook features 25 Op-amp Circuits And Projects which explore different applications of the operational amplifier IC.

Today electronic projects for hobbyists and students are an essential part of their academics and these educational science experiments boost their skills and analytic power rapidly to a great extent and it has been used in thousands of applications and is extremely popular.

The 741 IC is one of the most rugged and low-cost operational-amplifier available in the market. The 741 op-amp IC is an integrated circuit (chip) used in a variety of amplifiers, sensor interfaces, oscillators, and many more applications.

The 741 IC can be used with a single DC power supply as well as a dual DC power supply and many project circuits in this eBook uses both types of power supplies. Connections of both types of power supplies using battery and how to connect it on a breadboard shown with photos/diagrams at the end of the eBook

BONUS: To support your project building work and to boost your knowledge, bonus materials such as understanding circuit diagrams, anatomy of a breadboard, how a breadboard and circuit work and practice circuit on a breadboard with actual photos and detailed explanation also included.
