Op-amp Circuits

Op-Amps  or Operational Amplifiers are called as the workhorse of Analog circuits. There are many types of Op-Amp IC, but the most commonly used ones are the LM358 and LM741. Based on the circuit design, Op-Amps can be configured for many applications like Amplifiers, Comparators, Integrators, Differentiators, Summer, Voltage Follower etc..  The below list from Circuit Digest consists of a huge collection of Op-amp Circuits with neat circuit diagram and practical DIY hardware explanation enabling you to master the operational amplifier basics.
