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

Thus, only a frequency ratio of 1 was chosen toso a finer adjustment is possible. XR data sheet provides complete basic circuit for a simple function generator. With the frequency-determining capacitor of 0.

The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. Although this is an analogue IC, this project just made it into the Arduino section of my website because it uses zr ATmega as a frequency counter and to drive an 8-digit 0. The frequency must be adjustable and at least cover the low frequency range.

It is a very useful bench test equipment for testing and datasyeet out the frequency of various devices with unknown frequency such as oscillators, radio receivers, transmitters, function generators, crystals, etc.

Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket. 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 low-cost IC XR provides a very simple function generator with only a few external components. A common function generator provides sine, for example, triangular and square waves. But there are some points that could improve it take to build an almost professional function generator.


This Datasbeet Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors. The output waveforms can be both amplitude and frequency dataxheet.

Function Generator with XR2206

All required circuit details dataxheet shown in the datasheet. For measurement purposes in the electronics laboratory is needed again and again signals of different frequency and waveforms. Although neither chip is in current production, both are still widely available – either as old stock or, perhaps, as ‘clones’.

Function Generator with XR It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors. 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.

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

It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard dtasheet can be used for connecting various sensors and connectors. Although I’ve seen circuits and even commercial project kits claiming several MHz frequency datasgeet, 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.

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 overlapping of the ranges isn’t ideal but it hasn’t proven datahseet be a problem in practice. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored.


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

Many attempts have come out with this simple circuit. It requires an operating voltage of 12 V and delivers sine and square wave signals. With the component values 2026 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. A sine-shaping network makes the triangular signal of the VCO, a sinusoidal signal that can be picked up at the pin 2.

It can be connected dataheet any type of stereo audio datashete 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.

At pin 3 to set the exact medium voltage and the output amplitude. The actual sample structure differs in some details from the data sheet. The additional output at pin 11 also delivers a square wave with the same frequency. The frequency is changed by using a variable resistor.

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. 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.
