Function Generator Circuit Using Op Amp

Function generator is a signal generator that produces various specific waveforms for test purposes over a wide range of frequencies.

Function generator circuit using op amp.

Working of function generator circuit. Function generator using op amp lm1458. In laboratory type function generator generally one of the function sine triangle etc is generated using dedicated chips or standard circuits and converts it in to required signal. We have already designed sine wave generator circuit square wave generator circuit and sawtooth wave generator circuit.

U1a and u1b form a triangle wave square wave oscillator respectively. For example one could generate a sinusoidal signal at 60hz. This function generator circuit will come in handy for those who want to build a simple cost effective function generator by their own. 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.

First a function generator also called a tone generator is an electronic device that can output a specific waveform at a set frequency. The simple function generator two waveform it produces triangle and square waves from 1hz up to 1mhz. The lm1458 does not require an external frequency compensation circuit and has built in short circuit. The two opamps inside lm1458 has a common bias network power supply line and are independent of each other in operation.

To see how this circuit operates in real life see the video below. A simple function generator circuit using lm1458 is known here. This circuit was built around a quad op amp ic max494 which takes less supply for operation. Lm1458 is a dual general purpose operational amplifier.

Function generator or waveform generator is an integral part of electronics and used to produce various kinds of waveforms like a sine wave square wave sawtooth wave etc. The function generator is pretty solid for all basic purposes such as home use. Function generator system can be readily synthesized using operational amplifiers on an approach which uses full when the need for a special purpose generator arises or when a function generator is inconvenient or prohibited by cost consideration. Now in this tutorial we will show you how to.

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 signals produced can be of very high quality. That circuit is based on a lm1458 or rc4558 capable of producing sine square triangular sawtooth and pulse waveforms of high accuracy and stability. And this is how a function generator circuit can be built with an lm324 op amp chip.
