Function Generator Circuit Using Op Amp

This function generator circuit will come in handy for those who want to build a simple cost effective function generator by their own.

Function generator circuit using op amp. We have already designed sine wave generator circuit square wave generator circuit and sawtooth wave generator circuit. You can use it to test the inner workings of audio amplifiers find the characteristic of op amps and diodes make funky noises the list of. To see how this circuit operates in real life see the video below. For example one could generate a sinusoidal signal at 60hz.

This circuit was built around a quad op amp ic max494 which takes less supply for operation. The basic wave shapes produced by most function generators are square wave triangular wave. The two opamps inside lm1458 has a common bias network power supply line and are independent of each other in operation. 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.

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. Lm1458 is a dual general purpose operational amplifier. 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. The lm1458 does not require an external frequency compensation circuit and has built in short circuit.

The signals produced can be of very high quality. And this is how a function generator circuit can be built with an lm324 op amp chip. That circuit is based on a lm1458 or rc4558 capable of producing sine square triangular sawtooth and pulse waveforms of high accuracy and stability. Simple function generator by lm566.

First a function generator also called a tone generator is an electronic device that can output a specific waveform at a set frequency. A simple function generator circuit using lm1458 is known here. U1a and u1b form a triangle wave square wave oscillator respectively. 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.

Function generator is a signal generator that produces various specific waveforms for test purposes over a wide range of frequencies. 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 simple function generator two waveform it produces triangle and square waves from 1hz up to 1mhz. Working of function generator circuit.
