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.

The frequency is set by a capacitor, in the range 0. It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors.

XR2206 Function Generator

The DC bias at this input is necessary, and the signal amplitude must be properly adjusted. 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. Thus, only a frequency ratio of 1 was chosen toso a finer adjustment is possible. The output was centered on 6. The capacitor C and the power to determine the frequency at pin 7.

There are integrated circuits that produce sine waves, although they are really relaxation oscillators and the sine waves come from shaping a triangle wave. FM would also be good for testing a phase-locked loop.

But there are some points that could improve it take to build an almost professional function generator. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. The output can be buffered to adjust its DC component and signal amplitude. The amplitude setting at pin 3 is connected with fixed resistors, so the output voltage is always the same. There are actually two timing resistors, and which one is used is selected by the level on pin 9.

The kHz signal could be picked up on an AM radio at the expected frequency, and the modulation heard. 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. All required circuit details are shown in the datasheet.

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

Feed Y and the XR with a triangle wave, and X by the rectified voltage across the tuned circuit. One could make a small AM radio transmitter with this chip for use over short distances.

For this project, I was more interested in producing a clean undistorted sinewave rather than pushing it to the limits in terms of frequency. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors. Use a buffered potentiometer to test the dependence of frequency on VC.

The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors. With the component values shown above, the overlapping frequency ranges are shown in the following table: 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.

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 darasheet stereo system to transmit stereo sound with excellent clarity throughout your home, office, yard or camp ground.

Cr2206 XR makes a quite passable sine wave. Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket.

XR data sheet provides complete basic circuit for a simple function generator. 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 XR offers many satasheet for sine wave generation and modulation over a wide range of frequency.

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.

It also analyzes transistor’s characteristics such as voltage and gain. When pin 9 is below 0. Many attempts have come out with this simple circuit.

The XR has some interesting features that illustrate some of the topics mentioned in this page, so let’s examine this chip. It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors. Function Generator with XR The frequency must be adjustable and at least cover the low frequency range.

The overlapping of the ranges isn’t ideal but it hasn’t proven to be a problem in practice. Headphone amplifier is small enough to fit in Altoids tin datashete, and thanks to low power consumption may be supplied from a single 9V battery.

At pin 3 to set the exact medium voltage and the output amplitude. 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. Switching frequency ranges from about one switch Verification of a frequency scale Setting the output voltage through a second potentiometer Adjustment xg2206 minimize distortion of the sinusoidal signal Setting of the symmetry of the triangular signal 1Hz – 2MHz XR Function Generator Kit.

Arduino – XR Function Generator

The output waveforms can be both amplitude and frequency modulated. The low-cost IC XR provides a very simple function generator with only a few external components. If the applied voltage V is 3. This gives easy frequency-shift keying FSK by a logic input to pin 9. 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.

Supply VC from a function generator, setting the DC bias at 3. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors.

I found 10k and 0. In any case, do not exceed 3 mA from pin 7 or 8.
