Function Generator Circuit Using Xr2206

Currently it is more than adequate for a small home electronics hobby lab.

Function generator circuit using xr2206.

The frequency must be adjustable and at least cover the low frequency range. The simple function generator two waveform it produces triangle and square waves from 1hz up to 1mhz. Walmeck is a diy analogue function generator that is based on the xr2206 high precision ic. 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.

Frequency output can be fine tuned using p1 and p2 potentiometers. The xr2206 function generator circuit sine triangle square waveform generator the frequency range is 1hz to 1mhz. And can be adjusted by vr3 see circuit xr2206 function generator. Frequency of operation can be selected.

Simple function generator by lm566. 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. A common function generator provides sine for example triangular and square waves. Function generator using op amp lm1458.

The output waveforms can be both amplitude and frequency modulated by an external voltage. 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. Formerly you will find the signal generator is called the function generator for use one machine. That circuit is based on a lm1458 or rc4558 capable of producing sine square triangular sawtooth and pulse waveforms of high accuracy and stability.

The entire function generator is comprised of a single xr2206 monolithic ic and a limited number of passive circuit components. The low cost ic xr2206 provides a very simple function generator with only a few external components. Xr2206 function generator user manual 6 7 pdf author. The xr2206 diy kit.

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. Xr2206 data sheet provides complete basic circuit for a simple function generator. 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.
