The frequency is changed by using a variable resistor. With 2206 component values shown above, the overlapping frequency ranges are shown in the following table: Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket.

With a pot of 2 megohms and a fixed resistor of 1 kOhm variation gives a ratio of 1 to and may include a range of 10 Hz to 20 kHz sweep. The sample design renounces everything that is not absolutely necessary. The additional output at pin 11 also delivers a square wave with the same frequency.

The capacitor C and the power to determine the frequency at pin 7.

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 triangular signal of the VCO, a sinusoidal signal that can be picked up at the pin 2. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. Switching frequency ranges from about one switch Verification of a frequency scale Setting the output voltage through a second potentiometer Adjustment to minimize distortion of the sinusoidal signal Setting of the symmetry of the triangular signal 1Hz – datasheeh XR Function Generator Kit.

Function Generator with XR 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. It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors. Instead of the sine wave output is obtained after opening of S1 a triangular output wave.


A common function generator provides sine, for example, triangular and square waves. All required circuit details are shown in the datasheet. Although I’ve seen circuits and even commercial project dtasheet 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.

Function Generator with XR2206

dwtasheet On the board, the outputs of the circuit were placed in small wire loops, where the signals can be picked up directly with alligator clips. For measurement purposes in the electronics laboratory is needed again and again signals of different frequency and waveforms.

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 xf your home, office, yard or camp ground. It also analyzes transistor’s characteristics such as voltage and gain. With the frequency-determining capacitor of 0.

The actual sample structure differs in some details from the data sheet. The output waveforms can be both amplitude and frequency modulated. 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 overlapping of the ranges isn’t datsheet but it hasn’t proven to be a problem in practice. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors. The amplitude setting at pin 22006 is connected with fixed resistors, datahseet the output voltage is always the same. But there are some points that could improve it take to build an almost professional function generator.


XR data sheet provides complete basic circuit for a simple 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.

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.

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.

Many attempts have come out with this simple circuit. The meter is dwtasheet perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored.

Function Generator with XR

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. Thus, only a frequency ratio of 1 was chosen toso a finer adjustment is possible.

At pin 3 to set the exact medium voltage and the output amplitude. Although neither chip is in current production, both are still widely available – either as old stock or, perhaps, as ‘clones’. It requires an operating voltage of 12 V and delivers sine and square wave signals.

The low-cost IC XR provides a very simple function generator with only a few external components.
