All required circuit details are shown in the datasheet.
Function Generator with XR2206
The amplitude setting at pin 3 is connected with fixed resistors, so the output voltage is always the same. A sine-shaping network makes the triangular signal of the VCO, a sinusoidal signal that can be picked up at the pin 2.
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.
It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors.
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.
The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. The capacitor C and the power to determine the frequency at pin 7. 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’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors. The sample design renounces everything that is not absolutely necessary.
It also analyzes transistor’s characteristics such as voltage and gain. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors. 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.
Instead of the sine wave output is obtained after opening of S1 a triangular output wave. Arduino Prototype uses all standard through-hole xe 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. A common function generator provides sine, for example, triangular and square waves. With the frequency-determining capacitor of 0.
It requires an operating voltage of 12 V and delivers sine and square wave signals. Function Generator with XR At pin 3 to set the exact medium datqsheet and the output amplitude.
With the datasheeh values shown above, the overlapping frequency ranges are shown in the following table: 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.
The additional output at pin 11 also delivers a square wave with the same frequency. Although neither chip is in current production, both are still widely available – either as old stock or, perhaps, as ‘clones’. 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 dztasheet reasonably low-distortion sine waveform.
The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored.
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. The actual sample structure differs in some details from the data sheet. For measurement purposes in the electronics laboratory is needed again and again signals of different frequency and waveforms.
For this project, I was more interested in producing a clean undistorted sinewave rather than pushing it to the limits datassheet terms of frequency. 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 output waveforms can be both amplitude and frequency modulated. The frequency must be adjustable and at least cover the low frequency range.
Many attempts have come out with this simple circuit. 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 – 2MHz XR Function Generator Kit.

But there are some points that could improve it take to build an almost ddatasheet function generator. The overlapping of the ranges isn’t ideal but it hasn’t proven to be a problem in practice. XR data sheet provides complete basic circuit for datasheer simple function generator.
The frequency is changed by using a variable resistor. The low-cost IC XR provides a very simple function generator with only a few external components. Thus, only a frequency ratio of 1 was chosen toso a finer adjustment is possible.
