IC XR2206 DATASHEET PDF

The XR is a monolithic function generator integrated circuit capable of producing high quality sine, square, triangle, ramp, and pulse waveforms. This laboratory exercise will use the XR monolithic IC function generator. The manufacturer’s data sheet to analyze the requirements to set the frequency . The low-cost IC XR provides a very simple function generator with only a few external components. XR data sheet provides complete basic circuit for a.

The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. There are actually two timing resistors, and which one is used is selected by the level on pin 9. I simply put cr2206 end of the whip antenna of the small pocket radio near the output of datsaheet XR, and got plenty of signal.

Dstasheet XR offers many possibilities for sine wave generation and modulation over a wide range of frequency.

There are integrated circuits that produce sine waves, although they are really relaxation oscillators and the sine waves come from shaping a triangle zr2206. One is displaying frequency response on the scope–you might try this with a parallel resonant circuit. The chip is advertised to work down to 0.

With the frequency-determining capacitor of 0. A circuit datahseet testing the XR is shown at the right. Function Generator with XR For this project, I was more interested in producing a clean undistorted sinewave rather than pushing it to the limits in terms of frequency.

I used modulation at 1. The amplitude setting at pin 3 is connected with fixed resistors, so the output voltage is always the same. An increase in V lowers the frequency, and an increase raises it. It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors.

XR Function Generator

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 dataxheet stereo sound with excellent clarity throughout your home, office, yard or camp ground.

Instead of the sine wave output is obtained after opening of S1 a triangular output wave. With the component values shown dztasheet, the overlapping dayasheet ranges are shown in the following table: Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors.

If the amplitude is not set correctly, the waveform will have dataeheet tops or bottoms, or both. 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. Thus, only a frequency ratio of 1 was chosen toso a finer adjustment is possible. The waveform looks like a spring extending and contracting! 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.

Function Generator with XR2206

The overlapping of the ranges isn’t ideal but it hasn’t proven to be a problem in practice. Although neither chip is in current production, both are still widely available – either as old datqsheet or, perhaps, as ‘clones’. The frequency must be adjustable and at least cover the low frequency range. FM would also be good for testing a phase-locked loop.

R is the normal timing resisor, while RC handles the modulating current. 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 formula for the frequency is shown in the figure. Use a buffered potentiometer xrr2206 test the dependence of frequency on VC. It can produce a triangle wave, but this is really just a step towards the sine wave, and is seldom required.

It requires an operating voltage of 12 V and delivers sine and square wave signals. I found 10k and 0.

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. This circuit sets the average value of the output waveform here to 6. It also analyzes transistor’s characteristics such as voltage and gain.

The XR has an AM input at pin 1. The output waveforms can be both amplitude and frequency modulated. Headphone amplifier is small enough to fit in Altoids tin box, and thanks to low power consumption may be supplied from x2r206 single 9V battery.

Frequency can be varied by a range switch and a potentiometer, so datashret one could make a fairly useful function generator based on this chip, at low cost. One could make a small AM radio transmitter with this chip for use over short distances. The sample design renounces everything that is not absolutely necessary.
