XR2206 Function Generator

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 meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. The formula for the frequency is shown in the figure.

Feed Y and the XR with a triangle wave, and X by the rectified voltage across the tuned circuit. If the amplitude is not set correctly, the waveform will have flat tops or xf2206, or both.

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

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. The XR provides a datahseet wave at an open-collector output, as well as a sine ratasheet. The actual sample structure differs in some details from the data sheet.


A common function generator provides sine, for example, triangular and square waves. I found 10k and 0. A sine-shaping network makes the triangular signal of the VCO, a sinusoidal signal that can be picked up at the pin 2. The kHz signal could be picked up on an AM radio at the expected frequency, dahasheet the modulation heard.

Arduino – XR Function Generator

The XR makes a quite passable sine wave. Use a buffered potentiometer to test the dependence of frequency on VC. The XR has some interesting features that illustrate some of the topics mentioned in this page, so let’s examine this chip.

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.

The chip is advertised to work down to 0. There are actually two timing resistors, and which one is used is selected by the level on pin 9. This circuit sets the average value of the output waveform here to 6.

XR data sheet provides complete basic circuit for a simple function generator. But there are some points that could improve it take to build an almost professional function generator. One is displaying frequency datasheet on the scope–you might try this with a parallel resonant circuit.

If the applied voltage V is 3. 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 50k pot adjustment is also important. 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 dataasheet – 2MHz XR Function Generator Kit.


When pin 9 is open or above 2 V, the resistor called R1 is used. 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.

Function Generator with XR2206

It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors. For measurement purposes in the electronics laboratory is needed again and again signals of different frequency and waveforms. In any case, do not exceed 3 mA from pin 7 or 8. One could make a small AM radio transmitter with this chip for use over short distances.

The frequency must be adjustable and at least cover the low frequency range. It also analyzes transistor’s characteristics such as voltage and gain. Arduino Prototype uses datashert standard through-hole components for easy construction, two of which are hidden underneath IC socket. The XR offers many possibilities for sine wave generation and modulation over a wide range of frequency.

This LC Meter allows to measure incredibly small inductances making it perfect tool datasyeet making all types of RF coils and inductors. With the component values shown above, the overlapping frequency ranges are shown in the following table: It requires an operating voltage of 12 V and delivers sine and square wave signals.

The output frequency can be modulated by an external voltage using the circuit shown at the right.
