In this video i take a look at operational amplifiers of op-amps and try to discover why they re so great and useful.

These op-amps form the basis of so many reasons of analogue design. Using an op-amp with feedback it’s possible to create a huge number of different types of circuit from inverting and non-inverting amplifiers to filters, integrators, differentiators oscillators and so much more.

Also the variety of op amps available is huge: general purpose, high input impedance, FET input, low noise, low input offset, wide bandwidth and many more.
