I simply put the end of the whip antenna of the small pocket radio near the output of the XR, and got plenty of signal. The formula for the frequency is shown in the figure.

Function Generator with XR2206

FM would also be good for testing a phase-locked loop. The output waveforms can be both amplitude and frequency modulated. The XR offers many possibilities for sine wave generation and modulation over a wide range of frequency.

The additional output at pin 11 also delivers a square wave with the same frequency. With a xg2206 of 2 megohms and a fixed resistor of 1 kOhm variation gives a dqtasheet of 1 to and may include a range of 10 Hz to 20 kHz sweep. Modulating the frequency with an external signal has quite a few applications.

Function Generator with XR

The chip is advertised to work down to 0. 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. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored.

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

In any case, do not exceed 3 mA from pin 7 or 8. The DC bias at this input is necessary, and the signal amplitude must be properly adjusted. The sample design renounces everything that is not absolutely necessary.

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. The XR has some interesting features that illustrate some of the topics mentioned in this page, so let’s examine this chip.

The XR makes a quite passable sine wave. This gives easy frequency-shift keying FSK by a logic input to pin 9. 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.

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. Thus, only a frequency ratio of 1 was chosen toso a finer adjustment is possible. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. XR data sheet provides complete basic circuit for a simple function generator.

Reducing R to 2k gave an ideal 20 ms period, or 50 Hz. Switching frequency ranges from about one switch Verification of a frequency scale Setting the output voltage dataheet 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.

Datashdet circuit for testing the XR is shown at the right. 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 low-cost IC XR provides a very simple function generator with only a few external components. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. The proper adjustment of these controls is necessary for a good-looking sine wave.

With the frequency-determining capacitor of 0. A common function generator provides sine, for example, triangular and square waves. Function Generator with XR I used modulation at 1.

Dtasheet VC from a function generator, setting the DC bias at 3. The XR has an AM input at pin 1. There are actually two timing resistors, and which one is used is selected by the level on pin 9.

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. Pins 7 and 8 are held at 3 V, and more than 3 mA should not be drawn from them, so 1k is the minimum timing resistor. An increase in V lowers the frequency, and an increase raises it. It also analyzes transistor’s characteristics such as voltage and gain.

When pin 9 is open or above 2 V, the resistor called R1 is used. If the applied voltage V is 3. This circuit sets the average value of the output waveform here to 6. One could make a small AM radio transmitter with this chip for use over short distances. The overlapping of datassheet ranges isn’t ideal but it hasn’t proven to be a problem in practice.

Frequency datasgeet 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 amplitude setting at pin 3 is connected with fixed resistors, so the output voltage is always the same. When pin 9 is below 0.
