Introduction
As a student of electronics, you might have used function generators in your college or university labs, but have you ever thought to make a little DIY function generator at home? If not, then why not now? Together with us, let us make a DIY Function Signal Generator using ICL8038. In case, you don’t know about the function generator; it is a piece of electronic test equipment that generates and delivers standard waveforms to a device under test, commonly sine and square waves. It can be used to verify that a piece of electrical equipment is operating properly or to test a design.
The ICL8038 is a function generator chip that can generate waveforms such as a triangle, square, sine, pulse, and sawtooth. These sine, square, and triangle wave shapes may all be created at the same time. Controlling parameters such as frequency, duty cycle, and distortion of these functions is possible. Thus, this is the greatest function generator circuit to start with for a novice
JLCPCB is the foremost PCB prototype & manufacturing company in china, providing us with the best service we have ever experienced regarding (Quality, Price Service & Time).

Function Generator Circuit
Working Explanation
Through this DIY Function Signal Generator, With outstanding results With a minimal quantity of resistive and capacitive components, the function generator ICL8038 can generate sine, triangle, and square waves, as well as the frequency of the signal, duty cycle, and adjustable distortion sine wave. External resistors and capacitors are important in the operation of this circuit because they determine the frequency and duty cycle of the waveform generated. The potentiometers are also used to alter the frequency of some signal-generating elements.
Applications and Uses
- To generate different waveforms.
- To verify that a piece of electronic equipment is operating properly or to test a design.
