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.

With the component values shown above, the overlapping frequency ranges are shown in the following table: 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 actual sample structure differs in some details from the data sheet. 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.
One is displaying frequency response on the scope–you might try this with a parallel resonant circuit.
This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors. A common function xrr2206 provides sine, for example, triangular and square waves. When pin 9 is open xg2206 above 2 V, the resistor called R1 is used.
It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors. Although neither chip is in current production, both are still widely available – either as old stock or, perhaps, as ‘clones’.
At pin 3 to set the exact medium voltage and the output amplitude. It can produce a triangle wave, xr220 this is really just a step towards the sine wave, and is seldom required. For measurement purposes in the electronics laboratory is needed again and again signals of different frequency and waveforms.
Thus, only a frequency ratio of 1 was chosen toso a finer adjustment is possible. It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors.
When pin 9 is below 0. For this project, I was more interested in producing a clean undistorted sinewave rather than pushing it to the limits in terms of frequency. 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.
Function Generator with XR It also analyzes transistor’s characteristics such as voltage and gain. The 50k pot adjustment is also important. 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.
XR2206 Function Generator
Modulating the frequency with an external signal has quite a few applications. A circuit for testing the XR is shown at the right. The capacitor C and the power to determine the frequency at pin 7.
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. Although I’ve seen circuits datashret even commercial project kits claiming several MHz frequency range, in practice I think somewhere around kHz or kHz ci frequency is more realistic for these X2r206 while still maintaining a reasonably low-distortion sine waveform.
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 datasueet resistor. The output can be buffered to adjust its DC component and signal amplitude. The circuit includes an auto ranging as well as reset switch and produces very accurate datasheeet stable readings. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings.
The output frequency can be modulated by an external voltage using the circuit shown at the right. 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 proper adjustment of these controls is necessary for a good-looking sine wave.
It is a very datashet 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 meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. The frequency must be adjustable and at least cover the low frequency range.
The XR offers many darasheet for sine wave generation and modulation over a wide range of frequency.

Supply VC from a function generator, setting the DC bias at 3. The output was dataeheet on 6. 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.
