proportionality constant This circuit is therefore called an integrator.

17.6.5 Other Applications of Op-amps

There are many applications of op-amps in the field of electronics. Some of

them are mentioned below.

i. Current to voltage converter where the output voltage is proportional to the input current.
ii. Digital to analog converter.
iii. Analog computer which is constructed by using op-amp integrators and adders to solve
differential equations.
iv. Waveform generators or function generators. Function generators are also incorporated in
analog computers to solve non linear differential equations.
v. Oscillators and filters. The oscillators are used to generate repetitive alternating current and
