In this category posts about basic integrated circuits (ICs) are available which are used in most of electronics circuit. In that post, working of those ICs are explained.
Op-amp stands for operational amplifier. It is basically an amplifier and because it performs many mathematical operations, so it is called an operational amplifier. In the past time when digital computers were not available at that time different mathematical operations like addition, subtraction, integration, differentiation, etc were performed on these amplifiers. The figure shown below …
NE555 is the most popular integrated circuit (IC) for time related circuits, for example- generating square waves, tones, clock pulses, time delay, PWM signals, etc. It is used in most digital and analog circuits. The Basic 555 timer circuit diagram and its working are explained in this article. it is invented in 1971 by an …
