For this project, I was more interested in producing a clean undistorted sinewave rather than pushing it to the limits in terms of frequency. A sine-shaping network makes the 22206 signal of the VCO, a sinusoidal signal that can be picked up at the pin 2.

Thus, only a frequency ratio of 1 was chosen toso a finer adjustment is possible. On the board, the outputs of the circuit rx placed in small wire loops, where the signals can be picked up directly with alligator clips.

Function Generator with XR2206

XR data sheet provides complete basic circuit for a simple function generator. The frequency is changed by using a variable resistor.

You can control lights, fans, AC system, computer, printer, amplifier, robots, garage door, security systems, motor-driven curtains, motorized window blinds, door locks, sprinklers, motorized projection screens and anything else you can think of.

The output waveforms can be both amplitude and frequency modulated. Although I’ve seen circuits and even commercial project kits claiming several MHz frequency range, in practice I think somewhere around kHz or kHz maximum frequency is more realistic for these ICs while still maintaining a reasonably low-distortion sine waveform.

The amplitude setting at pin 3 is connected with fixed resistors, so the output voltage is always the same. It also analyzes transistor’s characteristics such as voltage and gain.

It requires an operating voltage of 12 V and delivers sine and square wave signals. The overlapping of the ranges isn’t ideal but it hasn’t proven to be a problem in practice. Switching frequency ranges from about one switch Verification of a frequency scale Setting the output voltage through a dqtasheet potentiometer Adjustment to minimize distortion of the sinusoidal signal Setting of the symmetry dataasheet the triangular signal 1Hz – 2MHz XR Function Generator Kit.


It is a very useful bench test equipment for testing and finding out the frequency of various devices with unknown frequency such as oscillators, radio receivers, transmitters, function generators, crystals, etc. The sample design renounces everything that is not absolutely necessary. Datashet there are some points that could improve it take to build an almost professional function generator.

All required circuit details are shown in the datasheet.

With a pot of 2 megohms and a fixed resistor of 1 kOhm variation gives a ratio of 1 to 22006 may include a range of 10 Hz to 20 kHz sweep. Headphone amplifier is small enough to fit in Altoids tin box, and thanks to low power consumption may be supplied from a single 9V battery.

For measurement purposes in x electronics laboratory is needed again and again signals of different frequency and waveforms. The additional output at pin 11 also delivers a square wave with the same frequency. It can be connected to any type of stereo audio source such as iPod, Computer, Laptop, CD Player, Walkman, Television, Satellite Datwsheet, Tape Deck or other stereo system to transmit stereo sound with excellent clarity throughout your home, office, yard or camp ground.

Arduino – XR Function Generator

It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings.

At pin 3 to set the exact medium voltage and the output amplitude. Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket. The actual sample structure differs in some details from the data sheet. The frequency must be adjustable and at least cover the low frequency range.


Although this is an analogue IC, this project just made it into the Arduino section of my website because it uses an ATmega as a frequency counter and to drive an 8-digit 0. Frequency control The frequency range is controlled with the timing capacitor connected between pins 5 and 6 of the XR and the timing resistors VR1, VR2 and R2 conencted in series between pin 7 and v. Datassheet the frequency-determining capacitor of 0. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored.

Many attempts have come out with this simple circuit.

It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors.

The low-cost IC XR provides a very simple function generator with only a few external components. Although neither chip is in current production, both are still widely available – either as old stock or, perhaps, as ‘clones’. A common function generator provides sine, datasheeg example, triangular and square waves.

The capacitor C and the power to determine the frequency at pin 7. With the component values shown above, the overlapping frequency ranges are shown in the following table: Instead of the sine wave output is obtained after opening of S1 a triangular output wave.
