Function Generator Circuit Using Op Amp

Lm1458 is a dual general purpose operational amplifier.

Function generator circuit using op amp.

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. 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. 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.

That circuit is based on a lm1458 or rc4558 capable of producing sine square triangular sawtooth and pulse waveforms of high accuracy and stability. This function generator circuit will come in handy for those who want to build a simple cost effective function generator by their own. We have already designed sine wave generator circuit square wave generator circuit and sawtooth wave generator circuit. And this is how a function generator circuit can be built with an lm324 op amp chip.

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. To see how this circuit operates in real life see the video below. 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. Now in this tutorial we will show you how to.

Function generator is a signal generator that produces various specific waveforms for test purposes over a wide range of frequencies. For example one could generate a sinusoidal signal at 60hz. Simple function generator by lm566. The signals produced can be of very high quality.

Function generator using op amp lm1458. 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. 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. Working of function generator circuit. First a function generator also called a tone generator is an electronic device that can output a specific waveform at a set frequency. The function generator is pretty solid for all basic purposes such as home use.
