Function Generator Circuit Using Xr2206

A common function generator provides sine for example triangular and square waves.

Function generator circuit using xr2206.

The output waveforms can be both amplitude and frequency modulated by an external voltage. Output volt adjusted by vr2 to built see pcb xr2206 function generator. The entire function generator is comprised of a single xr2206 monolithic ic and a limited number of passive circuit components. The xr2206 function generator circuit sine triangle square waveform generator the frequency range is 1hz to 1mhz.

Based on my experience the easy to build 1hz imhz xr2206 function generator kit allows a variety of routine measurements and experiments and offers fairer quality sine square and triangle output waveforms with moderate stability and accuracy. Function generator using op amp lm1458. Currently it is more than adequate for a small home electronics hobby lab. Xr2206 function generator user manual 6 7 pdf author.

Formerly you will find the signal generator is called the function generator for use one machine. Frequency output can be fine tuned using p1 and p2 potentiometers. The circuit around the xr 2206 is based on the exartan 005 xr 2206 application note which describes a high quality 1hz to 100khz function generator after playing with some of the component values and adding a couple of opamps i think the sine wave quality is acceptable up to 550khz although the triangle wave starts to get rounded peaks at. The simple function generator two waveform it produces triangle and square waves from 1hz up to 1mhz.

The low cost ic xr2206 provides a very simple function generator with only a few external components. Xr2206 data sheet provides complete basic circuit for a simple function generator. 1hz 2mhz xr2206 function generator kit includes premium quality components including audio grade gold capacitors gold plated rca connector wima capacitors 1 metal film resistors and premium quality pcb with red solder mask. The frequency must be adjustable and at least cover the low frequency range.

Simple function generator by lm566. The xr 2206 is a monolithic function generator integrated circuit capable of producing high quality sine square triangle ramp and pulse waveforms of high stability and accuracy. That circuit is based on a lm1458 or rc4558 capable of producing sine square triangular sawtooth and pulse waveforms of high accuracy and stability. Frequency of operation can be selected.

6 6 2018 11 40 39 pm. It can generate simple sine triangle and square waves of the frequency range 1hz to 1mhz the amplitude and frequency of the function generator can be adjusted with the help of fine tuning and coarse tuning using the knobs. It provides the engineer student or hobbyist with highly versatile laboratory instrument for waveform generation at a very small fraction of the cost of conventional function generators available today.
