Function Generator Circuit Using Op Amp

Function generator using op amp lm1458.

Function generator circuit using op amp.

The simple function generator two waveform it produces triangle and square waves from 1hz up to 1mhz. 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 basic wave shapes produced by most function generators are square wave triangular wave. 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.

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. This circuit was built around a quad op amp ic max494 which takes less supply for operation. A simple function generator circuit using lm1458 is known here. Lm1458 is a dual general purpose operational amplifier.

For example one could generate a sinusoidal signal at 60hz. The signals produced can be of very high quality. The lm1458 does not require an external frequency compensation circuit and has built in short 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.

First a function generator also called a tone generator is an electronic device that can output a specific waveform at a set frequency. This function generator circuit will come in handy for those who want to build a simple cost effective function generator by their own. And this is how a function generator circuit can be built with an lm324 op amp chip. Simple function generator by lm566.

U1a and u1b form a triangle wave square wave oscillator respectively. Now in this tutorial we will show you how to. We have already designed sine wave generator circuit square wave generator circuit and sawtooth wave generator circuit. To see how this circuit operates in real life see the video below.

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 two opamps inside lm1458 has a common bias network power supply line and are independent of each other in operation. Working of function generator circuit. Function generator is a signal generator that produces various specific waveforms for test purposes over a wide range of frequencies.
