Simple function generator by lm566.
Function generator circuit diagram.
The block diagram of a function generator is given in figure.
The triangular wave is generated by charging a capacitor using two constant current sources.
The function generator circuit we will build with an lm324 op amp chip is shown below.
As explained above the lm324 is powered by dc voltage through pins 4 and 11.
There are both high and low level outputs which may be adjusted with the level control.
The block diagram of a function generator is given in the figure.
Function generator circuit diagram with lm324 op amp the lm324 is a 14 pin integrated circuit the circuit diagram of the function generator with lm324 is shown below.
The circuit needs a dual power supply.
In this instrument the frequency is controlled by varying the magnitude of the current that drives the integrator.
The block diagram shows a triangular wave generator as the signal source.
So the first concern is power to the circuit.
Function generator circuit diagram parts list.
This instrument provides different types of waveforms such as sinusoidal triangular and square waves as its output signal with a frequency range of 0 01 hz to.
A 15 15 power supply as shown in the circuit is enough for the purpose.
That circuit is based on a lm1458 or rc4558 capable of producing sine square triangular sawtooth and pulse waveforms of high accuracy and stability.
The simple function generator two waveform it produces triangle and square waves from 1hz up to 1mhz.

So above is the function generator chip we will build.
Function generator ranging from 0 1 hz to 20 mhz can be easily built using max038 integrated circuit chip.
Usually function generators derive their frequency from a non sinusoidal oscillator.
The components required for this circuit are lm324 op amp chip two 10kω resistors four 100kω resistors 22kω resistor 220kω resistor 1μf ceramic capacitor 33 nf ceramic.
This instrument provides different types of waveforms such as sinusoidal triangular and square waves as its output signal with a.
In this instrument the frequency is controlled by varying the magnitude of current that drives the integrator.
The frequency of the output wave form can be adjusted using r7 it must be a 100k log pot.
This project makes a useful addition to any hobbyists workbench as well.
The breadboard circuit of the above circuit is shown below.
