The output was centered on 6.

The frequency must be adjustable and at least cover the low frequency range. With the component values shown above, the overlapping frequency ranges are shown in the following table: With the frequency-determining capacitor of 0.

Function Generator with XR2206

The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. The XR has some interesting features that illustrate some of the topics mentioned in this page, so let’s examine this chip.

At datasheet 3 to set the exact medium voltage and the output amplitude.

This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors. It requires an operating voltage of 12 V and delivers sine and square wave signals. The kHz signal could be picked up on an AM radio at the expected frequency, and the modulation heard.

Frequency can be varied by a range switch and a potentiometer, so that one could make a fairly useful function generator based on this chip, at low cost. It is a very useful bench test equipment for testing and finding out the frequency of various devices with unknown frequency such ddatasheet oscillators, radio receivers, transmitters, function generators, crystals, etc.

There are integrated circuits that produce sine waves, although they are really relaxation oscillators and the sine waves come from shaping a triangle wave. The formula for the frequency is shown in the figure.

For this project, I was more interested in producing a clean undistorted sinewave rather than pushing it to the limits in kc of frequency.

The 50k pot adjustment is also important. When pin 9 is below 0. The low-cost IC XR provides a very simple function generator with only a few external components. FM would also be good for testing a phase-locked loop. Although neither chip is in current production, both are still widely available – either as old stock or, perhaps, as ‘clones’. The frequency is changed by using a variable resistor.

The amplitude setting at pin 3 is connected with fixed resistors, so the output voltage is always the same. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. The proper adjustment of these controls is necessary for a good-looking sine wave. One could make a small AM radio transmitter with this chip for use over short distances. This circuit sets the average value of the output waveform here to 6.

There are actually two timing resistors, and which one is used is selected by the level on pin 9. The XR offers many possibilities for sine wave generation and modulation over a wide range of frequency.

If the applied voltage V is 3. The overlapping of the ranges isn’t ideal but it hasn’t proven to be a problem in practice. Reducing R to 2k gave an ideal 20 ms period, or 50 Hz. An increase in V lowers the frequency, and an increase raises it.

R is the normal timing resisor, while RC handles the modulating current. It also analyzes transistor’s characteristics such as voltage and gain. One is displaying frequency response on the scope–you might try this with a parallel resonant circuit.

Use a buffered potentiometer to test the dependence of frequency on VC. XR data sheet provides complete basic circuit for a simple function generator. The frequency is set by a capacitor, in the range 0. If the amplitude is not set correctly, the waveform will have flat tops or bottoms, or both. Function Generator with XR It can be connected to any type of stereo audio source such as iPod, Computer, Laptop, CD Player, Walkman, Television, Satellite Receiver, Tape Deck or other stereo system to transmit stereo sound with excellent clarity throughout your home, office, yard or camp ground.

Thus, only a frequency ratio of 1 was chosen tolc a finer adjustment is possible. The actual sample structure differs in some details from the data sheet. The XR has an AM input at pin 1. It can be connected to any type of stereo audio source such as iPod, Computer, Laptop, CD Player, Walkman, Television, Satellite Receiver, Tape Deck or other stereo system to transmit stereo sound with excellent clarity throughout your home, office, yard or camp ground.

22066 output frequency can be modulated by an external voltage using the circuit shown at the right. It also analyzes transistor’s characteristics such as voltage and gain. The output waveforms can be both amplitude and frequency modulated.

A common function generator provides sine, for example, triangular and square waves. A circuit for testing the XR is shown at the right. Many attempts have come out with this simple circuit. Instead of the sine wave output is obtained after opening of S1 a triangular output wave.
